When to use 'void main ()' and when to use 'int main ()' in C language ? Will anyone help me by posting examples, please.

I have seen that somewhere 'void main ()' is used and somewhere 'int main ()' with 'return 0'. In some compilers I also have found that after using 'int main ()' and then not using 'return 0' gives the correct output. Why ?

Always use int main(). void main() is just acceptable on some compilers.

Nice quote: " void main() is useful mainly as an indication that you're using a textbook written by someone who doesn't know the C language very well. " Source: https://stackoverflow.com/questions/18928279/how-does-int-main-and-void-main-work

@Martin - only int main() is standard C (and it has been like that from ANSI C89). void main() was kept around only for backwards compatibility, but you should avoid using it.

void main is for Turbo C++, and it's better not to use it.

"void main ()" is also used with the Arduino IDE rather than "int main ()".

void main is used when you want that your function should not return any value. However, if you want the function to return an int value, we use int main
