Question

我正在编写一个汽车经销商程序，在该程序中，您要求用户输入他们的选择（1.福特2.Mustang），但是它没有显示最终选择的内容，而是显示了数字选择。而不是显示“您选择了红色2015雪佛兰Malibu”或类似的名称，而是显示了“您选择了1 1 1 1”。这是代码。

UPDATE 我已经切换到用例，但仍然得到相同的输出。

#include <iostream>

using namespace std;

void cars();



int main()

{


int option;
cout << "Hello! Thank you for using CarRight Solutions!\n";
cout << "We have a nice selection of sudans to choose from. Press 1 to start 
your search for the right car. \n\n" << endl;
cout << "1. Cars\n";

    cin >> option;

    if (option == 1)
    {
         cars();
    }


system("pause");
return 0;

}

void cars ()
{
int make, model, year, color;



cout << "\n *****CARS SELECTION***** \n";

cout << "Select a make. \n" << endl;
cout << "1. Chevorlet \n";
cout << "2. Nissan \n";
cout << "3. Honda \n";
cout << "4. Toyota \n";


cin >> make;

switch (make) {
case 1:
    cout << "\n You have selected Chevorlet.\n";
    cout << "Please select a model. \n";
    cout << "1. Malibu \n";
    cout << "2. Impala \n";

    cin >> model;
    switch(model) {
    case 1:
        cout << "\n You have selected Malibu. \n";
        cout << "Please select a year. \n";
        cout << "1. 2017 \n";
        cout << "2. 2018 \n";
        cout << "3. 2019 \n";
    cin >> year;
    switch(year) {
    case 1:
        cout << "\n You have selected 2017. \n";
        cout << "Select a color. \n\n";
        cout << "1. Black \n";
        cout << "2. White \n";
        cout << "6. Blue \n";
    cin >> color;
    switch(color) {
    case 1:
        cout << "\n You have selected Black.\n";
        cout << "A" << color << "," << year << "," << make << "," << model 
    << " will be around $20,000.";
    }
    }
    }}}

输出仍然是： // A1,1,1,1约为20,000美元。

Answer 1

您打印“ make”值

cout << "\n You have selected" << make

但是您需要使用像这样的开关运算符

switch(make){

情况1：打破; 情况2：打破; }

用户答案选项显示数字选项，而不是数字？ C ++
