Answer 1

C++ CODE:

#include <iostream>

using namespace std;

int main() {

    string password;

    bool isLengthy = false, containsUppercase = false;

    // Get password from the user

    cout << "Enter your password: ";

    cin >> password;

    // Check if password is at least 8 characters long

    if (password.length() >= 8)

        isLengthy = true;

    // Check if password contain at least one uppercase letter

    for (int i = 0; i < password.length(); i++) {

        if (password[i] >= 'A' && password[i] <= 'Z') {

            containsUppercase = true;

            break;

        }

    }

    // If password is at least 8 characters long and contains an uppercase letter

    // then it is a strong password

    if (isLengthy && containsUppercase)

        cout << "Strong password\n";

    else

        cout << "Weak password\n";

    return 0;

}

OUTPUT:
