<code lang="C">
#include <stdio.h>

void repeat(unsigned int i, void routine(void))
{
        (*routine)();
        if(i > 1)
                repeat(i-1, routine);
}


void print(void)
{
        puts("This is fun");
}


int main(void)
{
        repeat(4, &print);
        return 0;
}
</code>

A for() loop is much nicer.
