Вопрос о массиве в C ++ для большего понимания предмета программирования

Я просто написал помощник Cli, чтобы легко справляться с Unix / windows.

Javascript:

define(["require", "exports"], function (require, exports) {
    /**
     * Helper to use the Command Line Interface (CLI) easily with both Windows and Unix environments.
     * Requires underscore or lodash as global through "_".
     */
    var Cli = (function () {
        function Cli() {}
            /**
             * Execute a CLI command.
             * Manage Windows and Unix environment and try to execute the command on both env if fails.

Example of use:

    Cli.execute(Grunt._command, args, function (command, args, env) {
        console.log('Grunt has been automatically executed. (' + env + ')');

    }, function (command, args, env) {

    }, function (command, args, env) {
        console.error('------------- Unix "' + command + '" command failed too. ---------------');
    });
