#includeThis example retrieves the value of the `-f` key, which is assumed to be a filename to be processed by the program. These examples use the `cppargparse` library for parsing command line arguments in C++.int main(int argc, char** argv) { cppargparse::ArgumentList args(argc, argv); std::string key = "-f"; std::string filename = args.GetStringKey(key); // open the file and do something with it return 0; }
