Question
Develop windows application for the ATM below. Implement the seven (7) functions listed below. Your application will have two windows, one to enter the PIN and one for main menu PIN window Tennessee State University Welcome to the Department of Computer Science's ATM Machine ENTER YOUR PIN PIN 2 5 8 3 CANCEL 6 CLEAR 9 4 7 0 ENTER PIN window is the first window to show when the user starts your program. The user will enter the PIN (initially 5100) and click on ENTER button. If the user would like cancel the typed PIN, s/he will click on CANCEL button. If s/he would like to erase the last digit/character entered, the CLEAR button should be clicked. The numbers can be entered from the keyboard or the virtual keyboard on the screen using the mouse. ENTER button to submit the PIN. If the PIN is correct, the system will show the next window, otherwise the user will be prompted the PIN is incorrect and s/he should try again. The limit of how many times the user can try the PIN is three (3). After three (3) failed attempts, your program should send an email to (kalnasr@tnstate.edu) withExplanation / Answer
