Modify this so that parent process calls waitpid() FOR EACH child before printing its hello to the world

#include #include #include int main pid_t child_1, child_2; child-1 = fork(); sleep(rand() % 5 +1); if (child_1) printf(" child 1 :-> Hello " else child-2 = fork(); sleep(rand() % 5 +1); if (child_20) printfC"child 2:HelloIn else return 0
