C++ 将 char 值设置为字符串？

Question

无论用户选择是否输入小写，这都会输出大写的“S”或“P”。当我与代码中的其他语句一起计算时，输出有效但是...我想在我的最终 cout 语句中显示 STANDARD 或 PREMIUM。

如何更改 char 的值以输出 STANDARD 或 PREMIUM？？？

#include <string>
#include <iostream>

char meal;

cout << endl << "Meal type:  standard or premium (S/P)?  ";
cin >> meal;

meal = toupper(meal);
    if (meal == 'S'){
      meal = 'S';
  }

    else{
      meal = 'P';
}

我试过 meal = 'Standard' 和 meal = 'Premium'它不起作用。

Answer 1

#include<iostream>
#include<string>
using namespace std;

int main(int argc, char* argv)
{
    char meal = '\0';
    cout << "Meal type:  standard or premium (s/p)?" << endl;;
    string mealLevel = "";
    cin >> meal;
    meal = toupper(meal);
    if (meal == 'S'){
        mealLevel = "Standard";
    }

    else{
        mealLevel = "Premium";
    }
    cout << mealLevel << endl;
    return 0;
}
