C ++ - 通过调用main（）函数重新启动游戏 [英] C++ - Restarting a game by calling the main() function

问题描述

我正在建立一个小游戏。
其中一个输入选项是重新启动游戏。我想到的唯一方法是从main函数中调用main函数。

I'm building a small game. One of the input options is to restart the game. The only way I could think of doing this was to call the main function from within the main function

int main(int argc, char argv[]) {
 ...
 if (input == "restart") {
  main(argc, argv);
 }

这是不良形式吗？

推荐答案

您不能调用 main（）递归。这实际上是未定义的行为。

You can't call main() recursively. That's actually undefined behavior.

使用循环代替：

int main() {
     bool restart = false;
     do {
         // Do stuff ...

         // Set restart according some condition inside of the loop
         if(condition == true) {
             restart = true;
         } // (or simplyfied restart = condtion;)
     } while(restart);
}
