What will be the output of the following C code?

#include <stdio.h>
void (*(f)())(int, float);
void (*(*x)())(int, float) = f;
void ((*y)(int, float));
void foo(int i, float f);
int main()
{
    y = x();
    y(1, 2);
}
void (*(f)())(int, float)
{
    return foo;
}
void foo(int i, float f)
{
    printf("%d %f\n", i, f);
}
