Difference Between Int Main And Void Main In C Programming

Difference between int main and void main

The standard statements are :-

int main()
void main()

Example ;-

#include
void main()
{
clrscr();
add(5,4);
getch();
}
int add(int a,int b)
{
int c;
c=a+b;
printf("Output: %d",c);
return 0;
}

now see the guys when you use the function having some parameters than time return some a and b values so now use int main function
if use void add(int a,int b) system throw the error. so i use int add(int a,int b)

Note :-

1. int main() is preferred over void main(), as per standards, and most new compilers supports int main() rather than void main().
2. int main() can help to return the error code if your program fails due to some error.
(Pre exception handling days, now you may use exception handling to handle issues,
perhaps that's the reason in java we go as public static void main () )
