if(fork) and if(!fork) - how do they work?
Let's say we have the following code: 
pid_t pid;
pid = fork();
if(pid == 0) {
        if(fork()) printf("A");
        else printf("B");
        printf("C");
}
else {
        if(!fork()) printf("A");
        else if (fork()) printf("B");
        else printf("C");
}
pid_t pid;
pid = fork();
if(pid == 0) {
        if(fork()) printf("A");
        else printf("B");
        printf("C");
}
else {
        if(!fork()) printf("A");
        else if (fork()) printf("B");
        else printf("C");
}
How many A's, B's and C's are going to be printed? I'm a little bit confused with how fork() works inside "if" and whether I'm in parent or child process.
