Why do we write int main void in C?

So the difference is, in C, int main() can be called with any number of arguments, but int main(void) can only be called without any argument. Although it doesn’t make any difference most of the times, using “int main(void)” is a recommended practice in C. Exercise: Predict the output of following C programs.

Why do we use int main () in C?

int main – ‘int main’ means that our function needs to return some integer at the end of the execution and we do so by returning 0 at the end of the program. 0 is the standard for the “successful execution of the program”. So, main is equivalent to int main in C89.

Do you need to void main in C?

On systems that don’t provide such a facility the return value is ignored, but that doesn’t make “void main()” legal C++ or legal C. Even if your compiler accepts “void main()” avoid it, or risk being considered ignorant by C and C++ programmers. In C++, main() need not contain an explicit return statement.

Can we use main () instead of int main ()?

Why void main is not used in C++?

Is void Main wrong?

Therefore, the designers could choose void main() and require the use of System. exit() for non-zero exit codes. So, the thing that would be “wrong” with choosing void main() for the C++ standard would be that it would break existing code that expected to use return and an exit code value from main() .
