Description

To turn debugging code on and off dynamically, create bool flags:

Demo Code

#include <iostream>
#include <string>
using namespace std;
bool debug = false;
int main(int argc, char* argv[]) {
   for(int i = 0; i < argc; i++)
      if(string(argv[i]) == "--debug=on")
        debug = true;
   bool go = true;
   while(go) {//from  w ww .  java 2 s. c o  m
      if(debug) {
         cout << "Debugger is now on!" << endl;
       } else {
          cout << "Debugger is now off." << endl;
       }
       cout << "Turn debugger [on/off/quit]: ";
       string reply;
       cin >> reply;
       if(reply == "on")
          debug = true; // Turn it on
       if(reply == "off")
          debug = false; // Off
       if(reply == "quit")
          break; // Out of 'while'
   }
}
