What will be the output of the program?

#include<stdio.h>
int main()
{
    int i=2;
    printf('%d, %d\n', ++i, ++i);
    return 0;
}

The order of evaluation of arguments passed to a function call is unspecified. Anyhow, we consider ++i, ++i are Right-to-Left associativity. The output of the program is 4, 3. In TurboC, the output will be 4, 3. In GCC, the output will be 4, 4.
