#includeThis code creates an `OptionsCont` object, adds three options, and then parses the command-line arguments. The resulting variables that were changed by parsing the options are outputted to the console. The package library for OptionsCont is Boost.#include "OptionsCont.h" using namespace std; int main(int argc, char** argv) { int width = 50; // default value int height = 20; // default value bool fullscreen = false; // default value OptionsCont options(argc, argv); options.addOption("width", 'w', "Set the width of the window", width); options.addOption("height", 'h', "Set the height of the window", height); options.addSwitch("fullscreen", 'f', "Enable fullscreen mode", fullscreen); options.parse(); cout << "Width: " << width << endl; cout << "Height: " << height << endl; if (fullscreen) cout << "Fullscreen: Enabled" << endl; else cout << "Fullscreen: Disabled" << endl; return 0; }
