用C++屏蔽windows终端中的密码输入

#include <iostream>
#include <string>
#include <conio.h>

std::string getPassword()
{
    std::string password;
    char ch;

    while ((ch = _getch()) != '\r') // 读取输入的字符，直到回车键被按下
    {
        if (ch == '\b') // 处理退格键
        {
            if (!password.empty())
            {
                password.pop_back();
                std::cout << "\b \b"; // 删除最后一个字符并移动光标
            }
        }
        else
        {
            password.push_back(ch);
            std::cout << '*'; // 用星号代替输入的字符
        }
    }

    std::cout << std::endl; // 换行

    return password;
}

int main()

    std::cout << "Enter password: ";
    std::string password = getPassword();
    std::cout << "Password entered: " << password << std::endl;

    return 0;
