#includeIn this example, we first create an instance of wxCmdLineParser and define a parameter named "FilePath" with a string value. We then call Parse() to parse the command line and check for any errors. Finally, we use the Found() method to retrieve the value of the "FilePath" parameter and print it to the console. Based on the syntax and the functions used in the example, it can be determined that the package library used for this example is the wxWidgets C++ GUI toolkit.int main(int argc, char** argv) { wxCmdLineParser parser(argc, argv); parser.AddParam("FilePath", wxCMD_LINE_VAL_STRING, wxCMD_LINE_PARAM_OPTIONAL); if (parser.Parse() != 0) { wxPrintf("Error: Invalid command-line arguments"); return -1; } wxString filePath; parser.Found("FilePath", &filePath); wxPrintf("File Path: %s\n", filePath); return 0; }
