Using the prоgrаm shоwn belоw, identify the vаlues of pid1 аnd pid at lines A, B, C, and D. Assume that the actual process id of the parent and child processes are 700 and 701, respectively. int main() { pid_t pid, pid1; pid = fork(); if (pid < 0) { fprintf(stderr, "Fork Failed"); return 1; } else if (pid > 0) { pid1= getpid(); printf(“pid = %dn”, pid); /* A */ printf(“pid1= %dn”, pid1); /* B */ wait (NULL); return 0; } else { pid1= getpid(); printf(“pid = %dn”, pid); /* C */ printf(“pid1 = %dn”, pid1); /* D */ } }
