            else
            {

                cout<<"Incorrect Password,Please Try Again :";

            }



    }
    cout<<"You Entered The Wrong Password More Than 3 Times!.Good Bye";
}

I am unable to get out of the loop,.eg if i choose i get the right password and enter the loop, following an option, i cannot choose another option.Please help

Start by declaring a boolean variable before the for-loop:

bool correct_pass = false;

Then, you set it to true inside the for-loop, when the password is correctly entered:

for (int i=0;i<3;i++)
{
    ...
    if (pass=2468)
    {
        correct_pass = true;
        break;
    }
    ...
}

Then you just check to see if the bool is true outside the for-loop (the break statement gets you out of the for-loop). You can then use another loop for the options menu.

As nmaillet implies, your loop should be only around your password test, not the entire program.
