#include <iostream>
#include "ArgParse/argparse.h"

int main(int argc, char** argv)
{
    auto parser = argparse::ArgumentParser("Program name").SetDescription("Description of program");
    parser.AddArgument(argparse::CreateNamedArgument().SetLongName("numbers").SetAnyNumberOfArgumentsButAtleastOne().SetType(argparse::ArgTypeCast::e_int));
    parser.AddArgument(argparse::CreateNamedArgument()
        .SetLongName("some_boring_long_name")
        .SetAnyNumberOfArgumentsButAtleastOne()
        .SetType(argparse::ArgTypeCast::e_int)
        .SetHelp("some_boring_long_name description with some important information for user.")
        .SetRequired(false));

    auto obj = parser.ParseArgs(argc, argv);
    if (obj.IsArgValid())
    {
        auto arg = obj.GetArg("numbers");
        if (arg.GetArgumentExists())
        {
            for (auto& el : arg.GetAsVecInt())
            {
                std::cout << el << std::endl;
            }
        }
    }
    else
    {
        std::string help = parser.GetHelp(80);
        std::cout << help << std::endl;
    }

    return 0;
}

This exmaple will create program with keys -n, --number, -s, --some_boring_long_name, -h and --help. Help will be autogenerated. The types of numbers and some_boring_long_name are integers with count from 1 to infinite.

Note actually terminal cannot get infinite numbers of arguments. In most cases maximum length of all input that terminal can pass is limited with 8 kb.
