C++ -使用用户输入的字符串数据检查结构字符串数据(无限执行while循环)

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

while (true) {
    // 在此处编写代码
}

string input;
cout << "请输入字符串数据：";
getline(cin, input);

string reversed = input;
reverse(reversed.begin(), reversed.end());
if (input == reversed) {
    cout << "输入的字符串是回文字符串" << endl;
} else {
    cout << "输入的字符串不是回文字符串" << endl;
}

char choice;
cout << "是否继续检查？(Y/N): ";
cin >> choice;
if (choice != 'Y' && choice != 'y') {
    break;
}
cin.ignore(); // 忽略之前输入的换行符

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

int main() {
    while (true) {
        string input;
        cout << "请输入字符串数据：";
        getline(cin, input);

        string reversed = input;
        reverse(reversed.begin(), reversed.end());
        if (input == reversed) {
            cout << "输入的字符串是回文字符串" << endl;
        } else {
            cout << "输入的字符串不是回文字符串" << endl;
        }

        char choice;
        cout << "是否继续检查？(Y/N): ";
        cin >> choice;
        if (choice != 'Y' && choice != 'y') {
            break;
        }
        cin.ignore();
    }

    return 0;
