Let's look at some example outputs for the program. Here the entire process sequence consists of process 18181: Sara@dell:~/OSSS$ ./linear 1 Creating process sequence of length 1. 18181 begins the sequence. An example for a sequence of length three: Sara@dell:~/OSSS$ ./linear 3 Creating process sequence of length 3. 18233 begins the sequence. 18234 is child of 18233 18235 is child of 18234 ........ this is coad .... BUt i could not compleate it .....:( #include #include #include #include int main(int argc, char *argv[]) { int N; pid_t pid; int cont; if (argc != 2) { printf("Wrong number of command-line parameters!\n"); return 1; } N = atoi(argv[1]); printf("Creating process sequence of length %d.\n",N); printf("%d begins the sequence.\n",getpid()); /* What I have to do next ?????? */ }
