Answer 2

Program to Request and Validate a Four-Digit Password

Here is a program written in C++ that prompts the user to enter a four-digit password and continues to request the password until it is entered correctly. The program uses an if-else statement to validate the password.

#include 
using namespace std;

int main() {
    int password;
    int correctPassword = 1234; // Replace with your desired password

do {
        cout << "Enter the four-digit password: ";
        cin >> password;

if (password == correctPassword) {
            cout << "Password accepted. Access granted." << endl;
            break;
        } else {
            cout << "Incorrect password. Please try again." << endl;
        }
    } while (true);

return 0;
}

To test the program, you can follow these steps: 1. Copy the code provided into a C++ compiler or IDE. 2. Compile and run the program. 3. Enter a four-digit password when prompted. 4. If the password is correct, the program will display "Password accepted. Access granted." and exit. 5. If the password is incorrect, the program will display "Incorrect password. Please try again." and prompt for a password again.

Please note that in the code provided, the correct password is set to 1234. You can change this value to any four-digit number of your choice by modifying the `correctPassword` variable.

I hope this helps! Let me know if you have any further questions.
