我的家庭作业程序应该包含一个带有几个选项的菜单，第一个是猜谜游戏，其次，将所有卡片打印在卡座3中……等等。 （请参阅下面的菜单）。我已经开始编写一些代码，并且已经测试了部分代码，并且它们一直在工作。现在，使用下面的整个程序，我无法执行该程序。如果有人能抽出一些时间来帮助解决问题以及可能包括的其他必备程序，我将不胜感激。不断出现以下错误消息：

答案 0 :(得分：0)
错误1：第163行
return 0;用于void函数。
错误2-4：第191、195、199行
settings1_Menu()
settings2_Menu()
settings3_Menu()
未定义。
与读取的错误完全相同。
不确定预编译头文件的问题，我根本没有真正使用过它们，并且该错误不在我的VS2015中。
此外，您已经注释掉了函数声明
//*void guess_Menu();
//void card_Menu();
//void leap_Menu();
//void func_Menu();
//void settings_Menu;
//*void menu_check();
阻止定义的编译，settings_Menu需要设置settings_Menu（），而menu_check（）未定义。
答案 1 :(得分：0)
lead_menu函数出现错误
void leap_Menu()
{
...
return 0;
}
您还注释掉了所有原型。因此，当编译器到达函数调用时，它不知道函数是什么。如果您不想使用原型，请查看内联函数
