Rewrite the program in Step 1. with two threads instead of two processes

#include /* printf, stderr */ #include /* pid_t */ #include /* fork */ #include /* atoi */ #include /* errno */ /* main function with command-line arguments to pass */ int main(int argc, char *argv[]) { pidut pid; int i, n = atoi(argv[1]); // n microseconds to input from keyboard for delay printf(" Before forking. "); pid = fork ; if (pid == -1) { fprintf(stderr, "can't fork, error %d ", errno); if (pid) { // Parent process for (i=0; i
