Confused with output of fork system call

Question

I have seen this piece of code on one of the forums and I'm finding it difficult to find the output of the given code. I'm really confused how do i go solve this particular line??

 fork() && fork() || fork();

#include <stdio.h>
#include <unistd.h>

int main()
{
    fork();
    fork() && fork() || fork();
    fork();

    printf("forked\n");
    return 0;
}
