追踪奇怪的错误

Question

我正在尝试做一些C++练习,但是我在构建时遇到了错误,这不仅仅是跳出来.我错过了什么？在几年前完成它之后,我只是从C#等回到C++.

[ERROR]语法错误:'return'[/ ERROR]

#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;
}

我不认为do while在C++中有这样的东西.是的do { ... } while (expression);.或者while (expression) { ... }.
