A project for C/C++, Data Structures, and System Programming by Karl Krauss for fall 2011.
This program only took about an hour.
The purpose of this project was to modify a program to work with processes using c.
This is the header file:
* */ #include<sys/types.h> #include<unistd.h> //#include<iostream> this is for c++ output and is not needed //#include<cstdlib> this is for c++ output and is not needed #include<sys/wait.h> #include<stdio.h> // need this for c IO #include<stdlib.h> // needed for c #define DINGLEHOPPER fork() #define SNARFBLAT wait(status) int main(int argc, char **argv) { int i = 0, *status; pid_t me; me = getpid(); if (argc < 2) { //std :: cout << "Please provide a list of positive unique whole numbers\n"; this is c++ output so removed printf("Please provide a list of positive unique whole numbers\n"); //c output added exit(1); } for(i=1; i<argc; i++) { DINGLEHOPPER; if(getpid() != me) { sleep(atoi(argv[i])); //std :: cout << atoi(argv[i]) << " "; c++ output so removed printf("%d ", atoi(argv[i])); // c output added exit(0); } } for(i=1; i<argc; i++) SNARFBLAT; //std :: cout << std :: endl; c++ output so removed printf("\n"); return(0); }
