- Functions are the subprograms of any complex problem which are developed independently and finally the solutions of all the subprograms will be integrated for final solution for the given problem.
Functions are of two types:
1) Predefined Functions
2) User Defined Functions
Also known as Modular Programming
Three points to be followed while implementing any userdefined functions
1) Function Declaration.
2) Function Call.
3) Function Definition.
Hi Viewers small mistake in program plz correct it.
In the add function I have written res =a+b and it was wrong as we are passing x , y as arguments
we have to write as res=x+y.
Thank u so much sir...I was struggling to understand basics but you explained it clearly :)
sir,should we declare x and y in function definition beside res?
hi yes we have to declare those x and y as parameters in the function because in the function declaration we have mentioned 2 arguments for the function call so the no. of parameters and function name in function declaration,function call and function definition should be same.
Hope your doubt has been clarified.
Actually sir when I am running this code in the main comes a error that is declaration syntax error
HI GARIMA
PLZ POST YOUR PROGRAM IN THIS COMMENT SECTION SO THAT I WILL TRY TO CLEAR IT.
I did not understand why some people dislike for this excellent teacher ~
thank you so much ,
love from MONGOLIA
Thank u Sir, I understood the Function Concepts in half an hour which I never understand whole semester.
A big thanks

Super sir. You explained it very nicely. Too good. Keep uploading such videos. It's really helpful. 👍👍👍👍

Sir go esay on board. Look at his enthusiasm 😂 .
Thankyou sir
You make very easy to understand this topic.
😊
Tq sir . I absent for functions class in my college but I see your video I understand the functions topic
U are awesome and ur videos are great makes learning c fun..great job sirji🎆🎆
Thank you very much..I have learned a lot from your video sir..
I like your way of teaching awesome 🙂
Excellent explanation sir
sir thank you very much i understood user defined function.and sir at 34:00 in the user defined function in the parameters the values of a and b are copied to x and y so in the user defined res=a+b; showed error,res=x+y; is the statement that is to be executed since x and y are the variables in the user defined( ) and not a and b.But you have corrected it when you did not return anything to main( ) in the next example.But i understood what you have explained.thanks a lot
Awesome sir
U got a new subscriber
It's excellent sir my total doubt s are cleared regarding this topic sir
Can we declare function in side main.function.
and in return type instead of int if we want to return float value can we declare
float function name( float a, float b)
Super sir...I understood the concept..
Sir apke har video bhut ache hote h.
Sir u teaching skills is excellent sir ,now i understood clearly while watching ur video tq sir pls keep uploading c concepts
ur way of teaching is awesome and easily catchable can u pls explain the concept of encapsulation and abstraction in C++
hi akshay
thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
now i am going to start uploading the videos on python programming. and after that i will try to upload them.
Wowwwwww...u cleared my 1 month class confusions in just 40 min ..I regret why did not I see your video earlier..just pray for me guys..my exams are coming up
sir in function declaration, is semi colon is not mandatory ?
thank you!
Sir a small.doubth...when the result is coping to sum at the end of execution then why to assign sum=0 on the above..
Sir in the function definition part having return type as int ,can we write res=x+y instead of res=a+b because i suppose both are equivalent statement because the value of a and b are automatically copied to the the variable x and y.
hi ankur
you are correct and in the function definition we are not supposed to use variables a & b as they are local variables declared in main function. i have written mistake there instead of writing res=x+y , i have written res=a=b.
thanks for correction and observation
thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
Sir small doubt !! For predefined function like printf and scanf we have to use void main ,then why you use only main() sir !! Without void main () is it ok sir !!!
Your class more useful sir.thanque very much.
You are great sir
Great explanation 👏
Sir which book should I refer to get a strong grip on c programming and where can I get question to practice it pls guide me
Excellent teaching.

Wonderful explanation sir.
Nyc teaching sir g💯❤️
super sir now I understand clearly .
tq sir
How to multiply matrices of user defined m*n order by passing functions?? Could you help us,
hi FPS
thanks for your interest towards our channel and soon i will upload it.
hi sir,can functional call is used for logic statement and i need some more examples on function call
Well explained sir.
Sir can we instialize variables in function declarations
Very nice teaching really good understanding sir
Super explanation sir.thank u sirr
sir does the output of the programme changes if we dont return a value instead return empty type
]
hi sai
if you write the output statement in the user-defined function itself, then return type is not required.
hope your doubt has been clarified.
wonderfully explained....🙂🙂
Thank u 💛
Sir, take a input in integer type and we declare a data in return type is float .it is possible or not
Sir can we write the function declaration without mentioning the datatypes inside the parenthesis ......as you said variables are optional inside the parenthesis ..is datatypes also optional
Void add(); - can we say this as function declaration
Sir calling function and function call are same ?? Or not ,if not why??
Sir can i put a+b insted of x+y in second program
Very good explanation Tysm sir ❤
Thank u sir... U teach well
hi M K
thanks for your interest and support towards our channel.keep following our channel.
Sir your teaching is awesome 👌 sir but giving examples also sir .giving values to a,b .we are understanding more sir
sir i am getting a this error - [Error] expected unqualified-id before '{' token
pls help sir.
at the end of 2nd row of code where function declaration ends semicolon(;) missed. placed the semicolon at the end of function declaration and execute the program . error will remove. regards #TARIQIQAL
very nice teaching sir.....thank u
Too much Beneficial to me😊😊
please add some more examples which makes us easy to understand
Very good explaination .. thnk u
Sir which book u r refereeing sir?
Sir please upload a video on Implicit and explicit functions
Very well teach sir👍
U r just above average
Thank you sir..I struggled a lot....Finally your video made me understand..
sir small doubt can actual parameters be called arguments???
Awesome sir..thank you so much sir
Tq sir.. It was very useful
Sir you are teaching excellent
Sir I'm not getting the output. It's showing some error, is there any mistake.?
Super sir ,thank you..
Great explanation sir☺☺
U cleared my doubt
how does compiler know re and sum are the same?
We need more advanced topics in this functions topics
In the place of res=a+b it will be res=x+y
Yes
I think we will write x+y also y because the values will change after the loop breaks when we enter into another loop so ur answer is correct and in my point of view it's correct I think
Very good explanation
