c++ - VIsual Studio 说我在字符串中有错误

Question

#include "stdafx.h"
#include <iostream>

using namespace std;

int main() {
    int temp;
    string phase;
    cout << "the temperature is: ";
    cin >> temp;

    if (temp > 0 && temp < 100) {
        phase = "liquid";

    }
    else if (temp < 0)
        phase = "ice";
    else
        phase = "gas";

    cout << "the phase is :" << phase << endl; 


    return 0;
}

我写的是 C++，但无法显示变量 phase 。这也会停止编译器，我无法编译它。

#include "stdafx.h"
#include <iostream>
#include <string>

using namespace std;

int main() {
    int temp;
    string phase;
    cout << "the temperature is: ";
    cin >> temp;

    if (temp > 0 && temp < 100) {
        phase = "liquid";

    }
    else if (temp < 0)
        phase = "ice";
    else
        phase = "gas";

    cout << "the phase is :" << phase << endl; 


    return 0;
}
