我可以建议使用模板化的c++命令行解析器库(GitHub上的一些分支是可用的)，API非常直接并且(引用自网站):

该库完全在头文件中实现，因此很容易 与其他软件一起使用和分发。它是MIT授权的 无后顾之忧的发行许可证。

这是手册中的一个例子，为了简单起见，这里有颜色:

#include <string>
#include <iostream>
#include <algorithm>
#include <tclap/CmdLine.h>

int main(int argc, char** argv)
{

    // Wrap everything in a try block.  Do this every time,
    // because exceptions will be thrown for problems.
    try {

    // Define the command line object, and insert a message
    // that describes the program. The "Command description message"
    // is printed last in the help text. The second argument is the
    // delimiter (usually space) and the last one is the version number.
    // The CmdLine object parses the argv array based on the Arg objects
    // that it contains.
    TCLAP::CmdLine cmd("Command description message", ' ', "0.9");

    // Define a value argument and add it to the command line.
    // A value arg defines a flag and a type of value that it expects,
    // such as "-n Bishop".
    TCLAP::ValueArg<std::string> nameArg("n","name","Name to print",true,"homer","string");

    // Add the argument nameArg to the CmdLine object. The CmdLine object
    // uses this Arg to parse the command line.
    cmd.add( nameArg );

    // Define a switch and add it to the command line.
    // A switch arg is a boolean argument and only defines a flag that
    // indicates true or false.  In this example the SwitchArg adds itself
    // to the CmdLine object as part of the constructor.  This eliminates
    // the need to call the cmd.add() method.  All args have support in
    // their constructors to add themselves directly to the CmdLine object.
    // It doesn't matter which idiom you choose, they accomplish the same thing.
    TCLAP::SwitchArg reverseSwitch("r","reverse","Print name backwards", cmd, false);

    // Parse the argv array.
    cmd.parse( argc, argv );

    // Get the value parsed by each arg.
    std::string name = nameArg.getValue();
    bool reverseName = reverseSwitch.getValue();

    // Do what you intend.
    if ( reverseName )
    {
            std::reverse(name.begin(),name.end());
            std::cout << "My name (spelled backwards) is: " << name << std::endl;
    }
    else
            std::cout << "My name is: " << name << std::endl;


    } catch (TCLAP::ArgException &e)  // catch any exceptions
    { std::cerr << "error: " << e.error() << " for arg " << e.argId() << std::endl; }
}

您可以使用GNU GetOpt (LGPL)或各种c++端口之一，例如getoptpp (GPL)。

一个简单的例子使用GetOpt你想要的东西(prog [-ab] input)如下:

// C Libraries:
#include <string>
#include <iostream>
#include <unistd.h>

// Namespaces:
using namespace std;

int main(int argc, char** argv) {
    int opt;
    string input = "";
    bool flagA = false;
    bool flagB = false;

    // Retrieve the (non-option) argument:
    if ( (argc <= 1) || (argv[argc-1] == NULL) || (argv[argc-1][0] == '-') ) {  // there is NO input...
        cerr << "No argument provided!" << endl;
        //return 1;
    }
    else {  // there is an input...
        input = argv[argc-1];
    }

    // Debug:
    cout << "input = " << input << endl;

    // Shut GetOpt error messages down (return '?'): 
    opterr = 0;

    // Retrieve the options:
    while ( (opt = getopt(argc, argv, "ab")) != -1 ) {  // for each option...
        switch ( opt ) {
            case 'a':
                    flagA = true;
                break;
            case 'b':
                    flagB = true;
                break;
            case '?':  // unknown option...
                    cerr << "Unknown option: '" << char(optopt) << "'!" << endl;
                break;
        }
    }

    // Debug:
    cout << "flagA = " << flagA << endl;
    cout << "flagB = " << flagB << endl;

    return 0;
}

尝试CLPP库。它是用于命令行参数解析的简单而灵活的库。仅头部和跨平台。仅使用ISO c++和Boost c++库。恕我直言，这比Boost.Program_options简单。

图书馆:http://sourceforge.net/projects/clp-parser

2010年10月26日-新发布2.0rc。修正了许多bug，完整的源代码重构、文档、示例和注释都得到了修正。

我发现使用ezOptionParser更容易。它也是一个单头文件，只依赖于STL，适用于Windows和Linux(很可能也适用于其他平台)，由于这些示例，它没有学习曲线，具有其他库没有的特性(如带有注释的文件导入/导出、带有分隔符的任意选项名称、自动使用格式等)，并且是LGPL许可的。

如果你可以使用boost库，我推荐boost::program_options。

在STL和常规的c++ /C运行时库中都没有特定的东西。

TCLAP是一个非常好的轻量级设计，易于使用: http://tclap.sourceforge.net/
