no need for an array, just a pointer is enough.

#include <stdio.h>

int main()
{
        char filename[] =3D __FILE__, *basename;
        basename =3D filename + sizeof(filename) - 2;
        while( basename+1 !=3D filename && *basename !=3D '/' ) {
                basename--;
        }
        basename++;
        printf("%s\n%s\n", filename, basename);
        return 0;
}
