Anyone know why this might not fuction as I thought it might.  It seems
to start at the beginning of main when a process is forked

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


int main( int argc, char * argv[]){
        pid_t pid;
        pid_t pid_ret;
        int i = 0;
        printf("\n___Before the While Loop where Loop is ==> %d__", i);

        while( i++ < 100){
                puts("\nBefore the Fork in the Loop:");
                printf( "Loop ==> %d \n", i);
                pid = fork();
                printf("\nFork: This should print twice for every loop:
%d", i);

        if(pid < 0){
                puts( "fork failed\n" );
                return 1;
        }
        if(pid == 0) {
                puts("\n\nChildren of the world unite");
                printf("Am Yisrael Chai! pid =>%d \n", pid);
                printf( "Loop in Child ==> %d \n", i);
                puts("BYE!!");
                exit( EXIT_SUCCESS );
        }
        if (pid > 0 ){
                printf("\nIn the  Parent => I'm waiting %d\n", pid );
                printf( "Loop in Parent ==> %d \n", i);
                pid_ret = wait(NULL);
                puts("Done Waiting for Child");
                printf("\nProcess that returned was ==> %d", pid_ret );
                printf("\n*******************************\n" );
        }
        }
        return 0;
}
