Sir after watching your video of pointers i have tried many other videos to get some more stuff. But after watching their videos i feel that NO ONE IS BETTER THAN YOU IN TEACHING C PROGRAMMING. SALUTE YOU SIR.
Sir, you are doing very good job.Helping those children who all can't afford to take tutions and even to those who all have quit on programming. God bless you sir and i'm saying all with my heart. May yo get,achieve whatever you want to :)
I never post a single comment on ur videos sir ,just because i dont have words to appreciate ur stuffs and such great explanation of all these concepts,rit now i m going through ur videos of 3 courses i.e c,c++,&data structure ,and i m going well just bcz of ur excellent and depth explanation of all topics......thanku very much sirrr....
Thank you so much sir for providing us such wonderful free knowledge of C language.Your way of teaching is amazing and systematically even a dull student can easily understand again thanku so much sir because of u sir now I am fully confident that I can give answer to any questions regarding C ❤️❤️❤️❤️❤️❤️
sir, if we assign a character variable with some low value,even then gets()takes accepts value>=char[i] and puts() also print it all ,then why we assign char[ ] value before
nicely explained sir. Sir if s in printf("%s",s) represents the base address of string ,then it should print only the base address character ,how does it prints the full string.
Vinay Pathak kuki y array bhi h ... or array k andr starting ka address mil jata h toh wo continue last tk print kra deta h .. string m bhi esa hi hua h isme starting ka address yani l &s[0] mil jata h or baki k liner tarike s print kr deta h
Sir thankuu so much for this wonderful video, before this video I was not able to understand string from anywhere. But after this my all doubts related to string can easily solved
in light way to understand the concept of string concept my request is see all the video note the every point which sir tell its seems to be the video is 17 min but the sir tells lots of concept so please see the video very carefully .....thank you sir
Sir ek doubt hai. (7:30) Jab aapne printf("%s",s); use kiya to pura string print hua to string me to null character bhi tha to uski vajah se ek space banna chahiye tha na SAURABH k baad jaise pehle loop use karke bana tha? Please correct me if I am getting it wrong.
doubt--sir jab aapne scanf("%s",&s[0]); likha toh kya compiler automatically samaj jayega ki first character ko &s[0] me daalna he then second character ko &s[1] me daalna he ...............and similarly last ith character ko &s[i] me daalna he
Sir... In programs why use int i,? If there is no looping there is no need to use this bcz we are not using this in program with int i, program can run nd it is giving the same output ..... Plz sir give me ans.....
Sir jaise hm use krte hai &s(0) puts me to isme to uska address print hona chahiye jaise aapne liya hai 1000 to ye put hona chahiye us address ki value print kraane k liye to hm * ka use krte hai
Dear Sir, thank u so much for your tutorials. But I have a question, how for() loop check the null character when it receives data from user. pls solve my query.
First of all thank you very much sir for given these largest knowledge Sir in this program you run whitout header file how it is possible Plz explain me
if string size which we have defined is less then the size of string which user has entered ,then what is exactly happening inside? Is it increasing the size of string automatically for example i defined char a[5]; and user enters a name abha saxena ,its size is more than 5 but still it is printing full name .
sir its gud but at 14:01 i didnt understand the concept like for adress s(0) its printing the content present in it and for normal s also its printing the value present in it ,are they one and the same? if so how can adress and the value in it are same
Sir should we always declare the size of string , length of string plus null character or we don't have to take extra cell for null character, and what if we don't take space for null character will it be created automatically sir please clear the doubt.
sir ....in this video, what is meaning of char s[20] in last the programe ? because it takes whole string whish has greater then 20 charactor or variable of string array.
hello sir for variables if we write &variable in printf it prints its address but why not in arrays or strings as here its printing the value of string??
Sir i always gets confused in string , can u tell me the problem in my code is ? :/ , //write a program which takes input of 5 countries and print them in alphabatic order .. #include #include main(){ char c[100]; int i,j; char tmp; //taking input for 5 countries .. for(i=0;i
sir, gets() is not working , what to do? I am using gcc compiler and running my code on linux terminal. The error is shown as "implicit declaration of gets() function ....gets function is dengerous and should not be used".
Sir mai kisi ek structure ke variable se us structure ke ek kisi structure variable jo ki charater array type ka hai, toh mai usko kaise input le sakta hu main function mei? gets karne se nahi aa raha hai input. blank input aur blank output aa raha hai.
Sir i have 1 question..if scanf cant print any char value after tab then we have to always use gets instead of scanf whenever we need to write after tab..kindly clear my doubt sir, I will be extremely thankful to u for this.
Sir i have a question. Sir mera question ha ke agr zero pehla variable ka element represent karta ha to printf("%s", s[0]) se baki ke varibles me moujood elements bhi kyo print ho jate hain.
sir.....i m prepairing for gate ................or agar aap ho tabhi me gate ki prepration kar pa raha hoon ....sir aapne jo knowledge free di hai aisa koi ni karta .....sir apne financialy weak bacho ka boht bhala kiya hai .. god bless you
i agree with u.
Use #include

so, how was your gate results?
Summary of the lecture:
String is a sequence of characters terminated at null character.
Null character is a special character whose ASCII value is 0.
While assigning letters to a character array,we explicitly write null character just to use it in looping condition,though it is not compulsory ,ex-
char a[10]={'a','b','c','\0'};
While assigning a string to a character array,no need to explicitly write null character,ex;-
char a[10]="ABC";
For printing the characters,
for(i=0;s[i]!='\0';i++)
printf("%c",s[i]);
NOTE:%c is a format specifier used to print only a single character(that is why we use a loop)
For printing a string
printf("%s",s);//s=base address
NOTE:%s is format specifier used to print only whole string(it takes base address of the array than access whole array to print the array)
VERY IMP:
Writing the name of the array represents first byte memory address of that array.
ex-
char s[10];
scanf("%s",s);//s= address of first byte of array(also known as base address)
Alternate function for printf:
puts(stringname)
puts is used to - print a string only and to send program control to new line after printing the string
Limitations of scanf:
takes space,enter or tab as delimeter
Alternate function for scanf:
gets(stringname)
takes only enter as a delimiter
Thank you !!
Thanks🙏🙇
Hats Off👍
We do not need to explicitly assign '\0' when defining a string letter-by-letter.
Dude you are awesome 👏
Awesome👏✊👍
You are truly an underrated youtuber

sir aapke padhane se maine c language sheek li.thanks sir
Same here
sir i like ur every lecture ur teaching is outstanding to understand any language easily
THANKS
Iqra Maryam pauan singh
Sir you are doing a great job
Thank you 😊
Thanks a million sir..ur videos are so helpful
sir aap ka ye ehshan kabhi nahi bholl payenge
god bless you sir ......may u live long
Sir bahut accha smjaya apne. .
Gr8. .👌
And give us questions related to topics discussion to solve.
Have you finished all lectures?
Sir that’s relly good that u tech us free and much better than any one
I never post a single comment on ur videos sir ,just because i dont have words to appreciate ur stuffs and such great explanation of all these concepts,rit now i m going through ur videos of 3 courses i.e c,c++,&data structure ,and i m going well just bcz of ur excellent and depth explanation of all topics......thanku very much sirrr....
Thank you so much sir for providing us such wonderful free knowledge of C language.Your way of teaching is amazing and systematically even a dull student can easily understand again thanku so much sir because of u sir now I am fully confident that I can give answer to any questions regarding C ❤️❤️❤️❤️❤️❤️
Very well explained sir....thanx a lot...to help us 🙏🙏🙏
saurabh sir, you are too good.. thank you very much for updating.............
we love you saurabh sir
Thanku very much sir ,I m in Iit but i don't find lectures and teaching methodolgy like u ...ur lectures are best .God bless u,dear sir
great sir I request you sir make more videos on string that includes user defined functions
Sir bhut acche se smjate ho ...concept clear ho jata hai
Sir 🙏🏻 you are great... Please asa hi padhaoo.. Video 🔥 🔥 🔥 🔥
sir, if we assign a character variable with some low value,even then gets()takes accepts value>=char[i] and puts() also print it all ,then why we assign char[ ] value before
To provide the compiler the base address of the string. Dono hi tarike se kar sakte hai....
Thank you very much. You are a genius. 👍👍🔝🔝
this video is the one of the best video for me ... Thankyou sir
nicely explained sir. Sir if s in printf("%s",s) represents the base address of string ,then it should print only the base address character ,how does it prints the full string.
Vinay Pathak kuki y array bhi h ... or array k andr starting ka address mil jata h toh wo continue last tk print kra deta h .. string m bhi esa hi hua h isme starting ka address yani l &s[0] mil jata h or baki k liner tarike s print kr deta h
bhai yahe difference hai array me aisa nhe hota bt string me hota hai isliya specifier s hai btagar specifier c kroge to na hoga
I always follow your every video.....And I would like to so much thank for you......Thank you...Thank you so much sir.........
thanks for making to strongs concepts.
it i best ref. to learn C.
Could we use for loop like scanf("%c",s) with i as counter variable while taking input from user???
Yes
sir awesome lecture i really like it please sir please upload more tutorial on union and enumulater
nicely explained sir!!! but.....
14:04 sir aapne printf m '&' kaise use kiya ye toh sirf hum scanf m use karte hai...???
sir...there is a warning of suspicious pointer conversion when using puts(s); what does it mean?
Sir thankuu so much for this wonderful video, before this video I was not able to understand string from anywhere. But after this my all doubts related to string can easily solved
in light way to understand the concept of string concept my request is see all the video note the every point which sir tell its seems to be the video is 17 min but the sir tells lots of concept so please see the video very carefully .....thank you sir

Sir ji love you because of you teaching
Sir truly it's great , understandable and lovely videos
dividing videos is a nice concept
Sir if I put space first and then enter any name will it give us a output
doubt--sir jab aapne scanf("%s",&s[0]); likha toh kya compiler automatically samaj jayega ki first character ko &s[0] me daalna he then second character ko &s[1] me daalna he ...............and similarly last ith character ko &s[i] me daalna he
Sir control string ke kya uddesy hai aur yh kase bnti hai aur kis prkar ki suchna prdan krti hai
Sir... In programs why use int i,? If there is no looping there is no need to use this bcz we are not using this in program with int i, program can run nd it is giving the same output ..... Plz sir give me ans.....
Very nice sir 😍😍
Sir jaise hm use krte hai &s(0) puts me to isme to uska address print hona chahiye jaise aapne liya hai 1000 to ye put hona chahiye us address ki value print kraane k liye to hm * ka use krte hai
very nice explanation sir!!...hats off to you
Dear Sir, thank u so much for your tutorials. But I have a question, how for() loop check the null character when it receives data from user. pls solve my query.
सर आपको कोटि-कोटि धन्यवाद्
Sir apki video se mujhe c programming samajh a gyi
your video is best for logical learning
Sir scanf me aapne S[0] use kiya he jisse first address mil jaye but int array me aisa kyu nahi kiya tha?
Thank you so much sir 🙏
First of all thank you very much sir for given these largest knowledge
Sir in this program you run whitout header file how it is possible
Plz explain me
sir g ka jaadu
Source file ka extension .C hai
sir aap bole ki printf("%s",&s[0])aur ("%s",s) likhna sam hai bt
first se to address print hona chaheya aur second se string ..???
Us address pe jo string hai wo print hoga, naki uska address
%d likha hota to address print hota shayad
Sir in later example of gets and puts where we are not using for loop do we have to initialize i
Outstanding teaching style
sir mai turbo me programmin karta ho to error dikhata hai aur code blocks me nahi to mai ky akaru
Sir kya gets() puts() ka bhi headerfile stdio.h hai?
sir how can we make a condition of factorial using recursions and pointers
if string size which we have defined is less then the size of string which user has entered ,then what is exactly happening inside? Is it increasing the size of string automatically
for example i defined
char a[5];
and user enters a name abha saxena ,its size is more than 5 but still it is printing full name .
sir aapne saurbh shukla print karwaya toh jo space de array uske liye bhi memory occupy karega ya nhi
sir its gud but at 14:01 i didnt understand the concept like for adress s(0) its printing the content present in it and for normal s also its printing the value present in it ,are they one and the same? if so how can adress and the value in it are same
Sir aap direct "main ( ) " function ka use kase karte he. Or program run ho jata he.please
sir g ka magic
Sir ismein aap scanf mein &s[0] kaise likh sakte hain kyunki puri string ke alag alag characters to s[0] s[1] s[2] s[3] aise alag alag address mein jayenge.
Sir should we always declare the size of string , length of string plus null character or we don't have to take extra cell for null character, and what if we don't take space for null character will it be created automatically sir please clear the doubt.
sir jab ham user se character input kara rahe han tab bhi kya compiler automatic hi null character ko jod deta h??
thank u sir i learnt a whole programming from your lectures\\\\\\.........
sir ....in this video, what is meaning of char s[20] in last the programe ?
because it takes whole string whish has greater then 20 charactor or variable of string array.
Sir apki video se string in c language samajh a gya
Thankyou sir. Aapke lectures outstanding h..
Bekar hai zuth mat bolo
#respect @sir ji you are evergreen awesome
scanf() sa kaya multiple word input nahi la sakta??
kasavi??
sir jb hm length nikal rhe hh kisi b do strings ki toh ye(gets) unke beech k space ko q count krra hh?
ex- mayank Raj
output- 10
Sir 14:00 per printf me address kyu kiya
&s[0] likha hai
Because s[0] and &s[0] are equivalent both represent the address.
For initialization after name saurabh putting \0 is compulsory ?
Thnxz
sir for loop ke bad curly braces ka use kab krenge or kab nhi?
Sir .. Jaise hm .. Int ke liye %d use krte h .. %f nhi kr sakte ..to .char me %s ... Kaise use kr sakte h ..
Sir in char type value we use %c ,in float use %F but sir in int case why do we use %d.
sir kya hm ek string ko dusri string m direct assing kra skte h jb dono string ki leanth same h
Thanku Sir ji
Happy teachers day sir ❤️
Very helpful video, sir😍
So good 👍 👍 👍 👍 👍
Tq sir u r vidios are very understandable.
Sir, without header file include kiye program kaise run ho rha hai? Hamara to error aa jata hai.
Sir, thanks for your help to learn the basics of string.....
Sir, can you please give us some examples of programs to understand it better .
hello sir
for variables if we write &variable in printf it prints its address but why not in arrays or strings as here its printing the value of string??
what happens if user input greater than size of string in c..plz reply sir
Sir String or Character array me kya difference hota hai?
Sir what is the main reason of using libraries of different names
sir your video is helpful.love from Pakistan
Sir i always gets confused in string , can u tell me the problem in my code is ? :/ ,
//write a program which takes input of 5 countries and print them in alphabatic order ..
#include
#include
main(){
char c[100];
int i,j;
char tmp;
//taking input for 5 countries ..
for(i=0;i
sir, gets() is not working , what to do? I am using gcc compiler and running my code on linux terminal.
The error is shown as "implicit declaration of gets() function ....gets function is dengerous and should not be used".
Sir mai kisi ek structure ke variable se us structure ke ek kisi structure variable jo ki charater array type ka hai, toh mai usko kaise input le sakta hu main function mei? gets karne se nahi aa raha hai input. blank input aur blank output aa raha hai.

Sir i have a question. Sir mera question ha ke agr zero pehla variable ka element represent karta ha to printf("%s", s[0]) se baki ke varibles me moujood elements bhi kyo print ho jate hain.
Kyuki variable lagatar m memory consume karke hn
