Prompt user for a password Read password from keyboard Check to see if the password is between 8 and 12 chars in length If length is ok loop through length of password check if char is a letter if so, set boolean that a letter has been found check if char is a digit if so set boolean that a digit has been found else if length is not ok then password is not valid and display this to console if there is no letter or no digit then display a message to consoled Search through history array to see if password is there if not check to see if history array is full if array is full, delete first element by moving each element up if the array is not full then add password to next empty slot and increment index Display message to console that password has been changed Test Password short Test Data too mick8 Expected result:
