unix/linux Study the following program. Determine if there is any compilation error. Compile and run with values for number of processes ranging fi s om 2 to 10 PROGRAM: DESCRIPTION: lab2.c This program generates a chain of processes using fork0. The number ofprocesses n is a command line argument. Each process sleeps for a random time less than 10 seconds then prints out */ process ID, parent ID, and child ID # include stdio.h» # include c:stdlib.h # include sys/types.h> int main(int argc, char *argvi) int i, m, n, sleeptime, seed; pid t childpid; if (argc!=2) { printi("in Usage: %s processes n", argv[0]); exit(1); n= atoi(argv[1]): m= 10; childpid = 0; for (i=0; in;i++) if (childpid = fork) break; if (childpid--1) { perror C"n The fork failedu); exit(1); parentid:9061d child ID:%61d",i, (long) getpid0, (long)getppido.
