why is child process running code meant for parent

The snippet below is being run by the child process as well but I don't know why because to my understanding the child's Pid should always be 0 so there's no reason for it to ever do anything below but print "I am child";

 pid_t child_Pid1 = fork();

 if((int)getpid() == 0) {
 printf("I am child\n");
 } else {
    printf("I am parent\n");
    }

getpid() always returns the current process's pid which is never zero, so in your current code, neither of the two processes does the execlp.

You want to look at child_Pid1 instead of getpid(). In the child it returns 0 instead of the child's pid.
