C++ 我如何将isValidPassword函数添加到此中？

我试图包含一个名为

isValidPassword

的函数，该函数将完成所有检查并返回一个布尔值，该值将指示密码是否有效

#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;


//  
bool isValidPassword(string list);

int main()
{
     string password;

     const int LENGTH = 101;
     char List[LENGTH];
     int Upper, Lower, Digit, Special;

    cout << "Create your password!\n"
         << "_____________________________________________\n"
         << "Passwords must meet the following criteria:\n" <<
         "_____________________________________________\n"
         << "- The password must have at least Tweleve characters.      ||\n"
         << "- The password must have at least one Uppercase letter.    ||\n"
         << "- The password must have at least one Lowercase letter.    ||\n"
         << "- The password must have at least one Digit.               ||\n"
         << "- The password must have at least one Special character.   ||\n";

    do
    {
        Upper = Lower = Digit = Special = 0;

        cout << endl << " Enter password: ";
        cin.getline(List, LENGTH);

        for (int i = 0; i < strlen(List); i++)
        {
            if (isupper(List[i]))
                Upper++;
            if (islower(List[i]))
                Lower++;
            if (isdigit(List[i]))
                Digit++;
            if (ispunct(List[i]))
                Special++;
        }

        if (strlen(List) < 12)
            cout << "Password needs to have at least twelve characters.        ||\n";
        if (Upper == 0)
            cout << "Password needs to have at least one uppercase letter.     ||\n";
        if (Lower == 0)
            cout << "Password needs to have at least one lowercase letter.     ||\n";
        if (Digit == 0)
            cout << "Password needs to have at least one digit.                ||\n";
        if (Special == 0)
            cout << "Password needs to have at least one special character.    ||\n";
    } while (Upper == 0 || Lower == 0 || Digit == 0 || Special == 0 || strlen(List) < 12);
}

bool isValidPassword(string password) {}

您只需要执行两个步骤：

1.从char[]转到std:：string

2.在函数中而不是在主函数中进行验证

#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
bool isValidPassword(string list);
int main()
{
    string password = "";
    cout << "Create your password!\n"
         << "_____________________________________________\n"
         << "Passwords must meet the following criteria:\n" <<
            "_____________________________________________\n"
         << "- The password must have at least Tweleve characters.      ||\n"
         << "- The password must have at least one Uppercase letter.    ||\n"
         << "- The password must have at least one Lowercase letter.    ||\n"
         << "- The password must have at least one Digit.               ||\n"
         << "- The password must have at least one Special character.   ||\n";
    do
    {
        cout << endl << " Enter password: ";
        cin >> password;

    } while (!isValidPassword(password));
    cout << "Password is valid!" << endl;
}

bool isValidPassword(string password) {
    if (password.length() < 12){
        cout << "Password needs to have at least twelve characters.        ||\n";
        return false;
    }
    int upper = 0;
    int lower = 0;
    int digit = 0;
    int special = 0;
    for (int i = 0; i < password.length(); i++)
    {
        if (isupper(password[i]))
            upper++;
        if (islower(password[i]))
            lower++;
        if (isdigit(password[i]))
            digit++;
        if (ispunct(password[i]))
            special++;
    }
    if (upper == 0){
        cout << "Password needs to have at least one uppercase letter.     ||\n";
        return false;
    }
    if (lower == 0){
        cout << "Password needs to have at least one lowercase letter.     ||\n";
        return false;
    }
    if (digit == 0){
        cout << "Password needs to have at least one digit.                ||\n";
        return false;
    }
    if (special == 0){
        cout << "Password needs to have at least one special character.    ||\n";
        return false;
    }
    return true;
}

看起来您在
main
中有一些全面的测试。您是否考虑过将它们移动到
isValidPassword
？您的问题是什么？您的代码的哪一部分不能按预期工作？不，它们不能。变量从您开始使用的任何法律字符开始。这是违反约定的，但不是违反规则的h导致编译错误。
