Question
**How to Write a BASIC Program for Username and Password Validation** This tutorial will guide you on how to write a BASIC program for validating the correct username and password. We will assume the known username is "Ali_Salah" and the password is "F@xt3L". If the wrong username or password is entered five times, the program will terminate. Upon entering the correct credentials, the program will print a welcome message. **Instructions:** 1. **Declare the Username and Password:** Define variables for storing the correct username and password. 2. **Input Loop:** Create a loop that allows the user to input the username and password. The loop will run up to five times for incorrect attempts. 3. **Validation:** Validate the entered username and password against the predefined values. If they match, print a welcome message and exit. If they do not match, increment the attempt counter. 4. **Termination:** If the user fails to enter the correct username and password in five attempts, the program will end. **Example Code:** ```basic 10 FOR attempts = 1 TO 5 20 INPUT "Enter Username: ", usrname$ 30 INPUT "Enter Password: ", passwd$ 40 IF usrname$ = "Ali_Salah" AND passwd$ = "F@xt3L" THEN GOTO 100 50 PRINT "Incorrect Username or Password. Try again." 60 NEXT attempts 70 PRINT "Access Denied. Too many failed attempts." 80 END 100 PRINT "Username & password are correct, Welcome." 110 END ``` **Explanation:** - **Line 10:** Start a loop that will run from 1 to 5. - **Line 20 & 30:** Prompt the user to enter the username and password. - **Line 40:** Check if the entered username and password match the predefined values. If they do, go to line 100. - **Line 50:** Inform the user that the credentials are incorrect and prompt them again. - **Line 60:** Move to the next attempt. - **Line 70:** If all five attempts are used without success, print an access denied message. - **Line 80:** End the program. - **Line 100:** Print a welcome message if the username and password are correct. - **Line 110:** End the program. By following these steps, you can efficiently create a BASIC program to validate usernames and passwords
