c++ - 追踪奇怪的错误

Question

我正在尝试做一些 C++ 练习，但我在构建时遇到了一个错误，这不只是突然出现在我身上。我错过了什么？在几年前完成之后，我刚刚从 C# 等人回到 C++。

[错误] 语法错误:“返回”[/错误]

#include <iostream>
using namespace std;

/* Pre-compiler directives / macros */
#define isValidDrinkChoice(Choice,MaxNumDrinks) ((Choice < MaxNumDrinks) && (Choice > 0))

/* Primary Entry Point for Executable */
int main(const int & argc, char * argv[]){

    const int MaxNumDrinks = 4;
    char ** Drinks;
    Drinks = new char* [MaxNumDrinks];
    Drinks[0] = "Soda";
    Drinks[1] = "Water";
    Drinks[2] = "Coffee";
    Drinks[3] = "Tea";
    Drinks[4] = "Perrier Sparkling Water";

    int Choice = -1;
    do while(!isValidDrinkChoice(Choice, MaxNumDrinks)) {
        cout << "Please select your favorite drink\r\n\r\n" << endl;
        for (int x = 0; x < MaxNumDrinks; x++) cout << "\t" << Drinks[x] << endl;
        cin >> Choice;
        if (isValidDrinkChoice(Choice, MaxNumDrinks)) cout << "\r\n\r\n" << "You chose " << *Drinks[Choice] << endl;
    }
    return 0;
}

Answer 1

我认为在 C++ 中没有像这样的do while。它是 do { ... } while (expression);。或者 while (expression) { ... } 。
