I was messing around with projects in xcode with C/C++ and I notcied this
#include <iostream.h>
int main (int argc, const char * argv[]) {
// insert code here...
cout << "Hello, World!\n";
return 0;
}
C++
and
#include <stdio.h>
int main (int argc, const char * argv[]) {
// insert code here...
printf("Hello, World!\n");
return 0;
}
C
So I've always sort of wondered about this, what exactly do those default arguments do in C/C++ under int main? I know that the application will still compile without them, but what purpose do they serve?
