8 processes containing 3 parents and 2 of them raise 3 children in C

Question

I’m having a hard time solving an exercise. I have to do a program that manages 3 parent lawsuits that in turn, two of them give rise to the creation of 3 child lawsuits. And in total, I have to generate 8 processes.

My problem is that I’m generating 9 processes and I can’t figure out why. Can you help me try to see the light? :)

Thank you!

    #include <stdio.h> 
    #include <sys/types.h> 
    #include <unistd.h> 
    
    int main(){
        int x = 2;
        pid_t p = fork(); 
        
        if (p == 0) {
            pid_t w = fork();
            x--;
        }  pid_t t = fork();
             if (t == 0){
                
            x+=3;
        }   else {
            pid_t s = fork(); 
    
        }      
        
        printf("x = %d -> PID = %d -> pai: %d \n", x, getpid(), getppid()); 
    
        sleep(1);
        return 0;
    }
