c++ - 字符数组的Initializer-String太长

Question

请帮助我完成我的编程最终项目。我的任务是制作餐厅POS系统。该程序上周运行良好，但是当我今天进行检查时，出现了错误，

在此文章中，“字符数组的初始化字符串太长”

char OptionLabels [][3] = {
    "Back to Menu",
    "Take Order",
    "Exit"
};

这是我的完整代码

看起来您通过尝试使用锯齿状数组(为什么？)使代码过于复杂，只需声明字符串数组即可:

string OptionLabels[] = {
    "Back to Menu",
    "Take Order",
    "Exit"
};
