Question

Is there a way to make this compile?

and make it so it uses the fct with an integer default?

using g++.

#include <stdio.h>

int     fct(int a = 0)
{
        printf("a: %d\n", a);
        return (0);
}

void    fct()
{
}



int     main(void)
{

        fct();
        return (0);
}

Answer 1

No, because once you added default value to fct(int) compiler can’t guess which one you want to call:

• fct(int) with default value of arg
• fct()

What you can do is remove default value, and call fct(0) or remove the one without arguments completely.
