Using the program in below, identify the values of pid at lines A, B, C, and D. (Assume that the actual pids of the parent and child are 1200 and 1203, respectively.)
#include <sys/types.h>
#include <stdio.h>
#include <unistd.h>
int main()
{
pid_t pid, pid1;
/* fork a child process */
pid = fork();
if (pid < 0) {
fprintf(stderr, "Failed");
return 1;
}
else if (pid == 0)
pid1 = getpid();
printf("child: pid = %d", pid); /* A */
printf("child: pid1 = %d", pid1); /* B */
}
else
pid1 = getpid();
printf("parent: pid = %d", pid); /* C */
printf("parent: pid1 = %d", pid1); /* D */
wait(NULL);
}
Return 0;
}
Ans)
A =
B =
C =
D =
