[C/C++] Using `getopt’ in c/c++

Using `getopt' in c/c++

Could not get the real original version for the examples, list one of them first, usefully and well tested.

ExamplesExample 1

// getopt_example.cpp#include <unistd.h>int main(int argc, char *argv[]){    int option = -1;    char *addr, *port;    while ((option = getopt (argc, argv, "i:p:")) != -1)    {         switch (option)         {         case 'i':             addr = strdup(optarg);             break;         case 'p':             port = strdup(optarg);             break;         default:              /* unrecognised option ... add your error condition */              break;         }    }    /* rest of program */    return 0;}
