The information for program.

#include #include #include // For pid_t #include // For wait()

int main() { pid_t pid;

/* fork a child process */ pid = fork();

if (pid == 0) { /* child process */ printf("Child "); return 0; } else { /* parent process */ wait(NULL); printf("Parent "); }

/* fork a child process */ pid = fork();

if (pid == 0) { /* child process */ printf("Child "); return 0; } else { /* parent process */ wait(NULL); printf("Parent "); } return 0; }
