Didi aapne c language ko bahut achhe se detail se padhaya hai aise aap c plus plus ka padha do n. Hum aap se padhna chahte hai c plus plus. Aapke padhane ka tarika bahut achha hai achhe se samjh me aata hai.
Those who are saying it prints Hello5, try running only int x= printf("Hello"); It will give 'Hello' as output, and if you write the complete code, it will print 'Hello5', meaning, 5 is the answer that x is returning
This video is very useful to meeru 🥳🥳. I hope to find more questions in it, not only in the C language but also in other programming languages for Interview a🙏🏻🙏🏻.
Let me explain that x: 5 and output : Hello5 Because In c, compiler execute first printf function then it return 5, Hello will print on execution. Then 5 will get assign to x, then last printf function print 5. As there is not any space or new line, it will print as Hello5. Printf function return the no. Of char
Hello5 is correct Output The Print statement hello will also be printed, talking about next statement, the length of HELLO that is 5 is printed after that without any space
@@AkankshaSumanofficial The code prints "Hello" and then a number on the next line. The printf("Hello ") function prints "Hello" and returns the number of characters it printed (6, including the newline ). This return value (6) is stored in the variable x. Then, printf("%d ", x) prints the value of x, which is 6.
It's nice to see that not only the first printf function prints the hello string but it also returns a value to complete the int x = code which the next printf function prints as 5 ❤
Some people are saying that the answer is Hello5 but the question is not that what is the output, but it is that what is x and the value of x is 5, not hello5.
Point 1: Output also includes hello and then 5 will be written like Hello5 Point2: printf also takes 'space' as a character If it was written like "Hello w" then printf will count 5+1+1 = 7 . Output is : Hello w7
Bete usne x ka value pucha hai na ki kya print hoga, Wo jo hello print horaha hao wo uper wali print statement ka ans hai aur uske bad x yani ki 5 print horaha hai, aur udhr new line statement nahi use ki hai isliye wo hello5 ek sath print hoarah hai
Certainly! Here's the corrected code that stores the value returned by `printf` in `x` and returns it: ```c #include int main() { int x = printf("hello"); printf("%d", x); return x; } ``` This code prints the length of the string "hello" followed by its actual length, and then returns the value of `x`. So the output will be: ``` hello5 ``` And the return value of the program will be `5`.
Int is an integer and not a character so only the number 5 will be printed as opposed to being an array of characters [ ] such as hello which is 5 characters. so printf function of hello will be printed and then the number of characters in number "5"
There's nothing to "think" about this. If you know you know lol. You may not be able to just guess the return value out of a random function (random because you typically wouldn't use it like this) right. Typically in systems languages, they usually return the "number of bytes written" from printing or writing functions. So there's that.
Quite simple problem for those who atleast knows the function signature of printf function it return an integer which is equal to number of characters that it has successfully printed in the console screen.
Jo printable cheeje hongi unka count number print hoga Jaise isme Hello ye sare printable hain Isiliye iska answer 5 aayega However isme \0 null character bhi hai but vo printable nhi hai isiliye vo is count me nhi add hoga

Actually Output is Hello5 because basically printf primarily does its work of printing the text and count the number characters which stores in x
Is there any way to print only number of characters not the original word in printf ??

First line will give output Hello and assign value to x then second line print 5 combine will be Hello5
5 because printed function returns lengthy of a string

Is shows error , bro int x sirf integer leta hai to int x ko ham print hello ko kaise print kr skte
Samjh to nahi aaya but sunke acha laga 😂😂😂

These small things make big difference in interview..
Let me explain that x: 5 and output : Hello5
Because In c, compiler execute first printf function then it return 5, Hello will print on execution.
Then 5 will get assign to x, then last printf function print 5.
As there is not any space or new line, it will print as Hello5.
Printf function return the no. Of char
Int x=(printf("hello world") , 18);
Was asked in iit kgp mid sem exam.
i guess that comma is of no use there
Same cheez hai, hello world hi print hoga
What is answer??
This is a simple type conversation, the string is a array of character, so it will return the amount of characters it has 😊
Didi @ApnaCollegeOfficial Correct answer is **Hello 5**
Because of %d is used length of *hello* also print.
Yss
Without space
But int return only integer walue how hello can home?
Hello5 not Hello 5 no spaces
In python
Output
Hello
None
Hello5 is correct Output
The Print statement hello will also be printed, talking about next statement, the length of HELLO that is 5 is printed after that without any space
In this question answer is "HELLO 5" BECAUSE value of int x is how many alphabet in Hello and hello is also print
Data type is int , so only integer value will be printed
Hello5 without space

The code prints "Hello" and then a number on the next line.
The printf("Hello
") function prints "Hello" and returns the number of characters it printed (6, including the newline
).
This return value (6) is stored in the variable x.
Then, printf("%d
", x) prints the value of x, which is 6.
One idea to take is, when we r printing the value of x we also used "%d" which represents an int so the output will be
hello5
5 = charector of str.
Yr kitni piyri h y...AGR issy hi coding sekhi hoti to aj m programer hota😊
Make a full length video of understanding this type of concepts
it will print Hello5 as output, cause printf("Hello"); print Hello and printf("Hello"); has 5 characters and 5 is stored in x. So output is Hello5.
It's nice to see that not only the first printf function prints the hello string but it also returns a value to complete the int x = code which the next printf function prints as 5 ❤

@@vivekdhamande8350 bro character nahi hai eiaha.😂
Ha bhai answer hello5 hi ayega isme x ka value kya print hoga questions ye hai uska answer hai 5
Some people are saying that the answer is Hello5 but the question is not that what is the output, but it is that what is x and the value of x is 5, not hello5.
Unhone poocha screen pe kya show hoga...
Aise hi logic question banate raho mam 😊
Point 1: Output also includes hello and then 5 will be written like Hello5
Point2: printf also takes 'space' as a character
If it was written like "Hello w" then printf will count 5+1+1 = 7 . Output is : Hello w7
Answer is " Hello5" not only 5 I also run the program
Bete usne x ka value pucha hai na ki kya print hoga,

Quite simple problem for those who atleast knows the function signature of printf function it return an integer which is equal to number of characters that it has successfully printed in the console screen.
Those who are messed up with c++ due to college teaching....😂
output is "hello5" but X is equals to 5
We can change int main to void main, then there will be no need to write any return value

Jo printable cheeje hongi unka count number print hoga
Jaise isme Hello ye sare printable hain Isiliye iska answer 5 aayega
However isme \0 null character bhi hai but vo printable nhi hai isiliye vo is count me nhi add hoga
5 , print function returns the length of the printed string
I am a beginner. If c++ is an extended of c ,then why we use “printf” and “cout” to output a statement.
Yup its simple thanks for sharing ❤
#include
int main() {
// Write C code here
int x= printf("Hello");
printf("%d", x);
return 0;
}
5?The answer should be Hello only right. Because we aren't giving any other command to print number of characters of the string.
DOUBT:
If we put (%f or %lf) instead of %d the output is Hello0.000000
Whats the reason?
%d indicates the integer value thats why 5 will be print
I don't know c but I know python and Java so I just tried and answered correctly
Its programming language specific question.. they questions are good for freshers and not for experienced developers.. 😂 these days people are asking inbuilt function's functionalities outcome

Mybe answer is 1(if printf is boolean function)
Or mybe ascii value of each digit

I predicted it right in those 3 sec.
Hello5 not just 5 because we are printing the string too
X is an variable and it's stored the statement that are *hellow world*.
Aaj meri class me yahi padhaya gaya tha❤❤❤
yes the x value is 5 .if we get this code output .than we have hello5 output
Output is-
Hello5
.. go run this code before starting any argument
Output :Hello5
Here 5 the number of characters in the string.
Int type stores integer values.
%d is used for int ..for printing numbers.
Intelligent
Thank you didi
Thanks 👍🏻
huh, matlab jitne character ka word hoga ye usse utne number me convert karke value provide karega?
Awesome
The ans is :_5 where (_) is space where printf("_%d"); there was a space there ans is a little bit of space 5
It doesn’t return number of characters but it returns number of bytes. RTFM
