密码长度验证(c++)

#include <iostream>
#include <string>

bool isPasswordValid(const std::string& password, int minLength) {
    return password.length() >= minLength;
}

int main() {
    std::string password;
    int minLength = 8; // 最小密码长度要求

    std::cout << "请输入密码：";
    std::cin >> password;

    if (isPasswordValid(password, minLength)) {
        std::cout << "密码有效！" << std::endl;
    } else {
        std::cout << "密码无效！密码长度至少应为" << minLength << "个字符。" << std::endl;
    }

    return 0;
