Thread: Return test

Whatever value i put in the if statement after return (0,1,-1) it comes back to
main().
So why is everybody putting all kind of values there?
Is it a prank on noobs?
Of course im not talking about values as a result of a calculation, that is different.

Code:

#include <iostream>

using namespace std;

int If(void)
{
    int a=2,b=2;
    if (a==b) {cout << "If...\n"  ; return 1;}
    else      {cout << "Else...\n"; return 0;}
}
int main()
{
    If();
    cout << "Main...\n";
    return 0;
}

A function is supposed to return the value to the calling function. It's only return from main that exits the program (since there is no calling function above that).

The main() return value indicates to calling envieronment whether program is terminated correctly, or something abnormal happened during the execution.
