Count the number of process created by fork()

Question

How to count the number of process created by system call fork() without using file writer. This is the code I'm trying but it doesn't work! It would be helpful to get some feedback. Thanks in advance.

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/wait.h>

int pid_count = 0;

int main(){
    pid_t pid = fork();
    pid_t pid2 = fork();
    
    if(pid == 0 || pid2 == 0){
        pid_count++;
    }
    
    if(pid > 0 || pid2 > 0){
        wait(NULL);
        printf("%d\n", pid_count);
    }
    
    return 0;
}

Output: 1 1 0
