Consider the following C program code (assume that fork() does not return an error). How many processes, including the parent process, will run during the execution of the code when the user inputs the value 2? #include #include #include int main() { unsigned int input, i, x; pid_t pid; X=1; X: scanf("%d",&input); if(input==1) { if(fork() && fork()) printf("CISC324 "); } else if(input==2) { for(i=3; i>0; i--) { pid = fork(); X = X * 2; printf("PID=%d: x=%d ", getpid(), x); } } else goto X; }
