boost :: program_options:如何获取应用程序名称？

#include <boost/program_options.hpp>
#include <iostream>

int main(int argc, char** argv) {
    namespace po = boost::program_options;

    // 定义命令行选项
    po::options_description desc("Allowed options");
    desc.add_options()
        ("help", "produce help message");

    // 解析命令行参数
    po::variables_map vm;
    po::store(po::parse_command_line(argc, argv, desc), vm);
    po::notify(vm);

    // 检查是否存在"help"选项
    if (vm.count("help")) {
        std::cout << "Usage: " << argv[0] << " [options]" << std::endl;
        std::cout << desc << std::endl;
        return 0;
    }

    // 获取应用程序名称
    std::string appName = boost::filesystem::basename(argv[0]);
    std::cout << "Application name: " << appName << std::endl;

    // 其他业务逻辑...

    return 0;
