C++ Logical Operators Exercise

Now based on what we have learnt let us try to create a login page.

The login page should ask the user to enter a username, password, and code if the username and either the password or code are correct to provide access.

Assume

password = admin123

username = admin

code=1234

Solution:


#include 
using namespace std;

int main ()
{
    string userName;
    string userPassword;
		int code;
    int loginAttempt = 0;

    while (loginAttempt < 5)//restricting number of time user enters wrong credentials
    {
        cout <<  "Please enter your user name: ";
        cin  >>  userName;
        cout <<  "Please enter your user password: ";
        cin  >>  userPassword;
				cout <<  "enter your code:";
				cin  >>   code;
				// to check if username and password is correct
        if (userName == "ADMIN") && (userPassword == "admin123" || code==1234)
        {
            cout << "Welcome ADMIN!\n";
            break;
        }
				else
				{
						cout<<"try again!!"<


Output:
Please enter your user name: ADMIN
Please enter your user password: sakmd
enter your code:1234
Welcome ADMIN!
Thank you for logging in.
