Question

Write a program that generates a random password that meets a certain criteria. the password should start with 7 or 8 or 9, and the next five digits can be any digit from 0 to 9. this should be followed by a dash (-) and then three random uppercase letters. hint: the integers from 65 to 90 represent the uppercase letters from a to z. you can cast an integer to a char type like this: (char)65 is 'a' and (char) 66 is 'b'

Answer 1

To create a random password with specific criteria, one can use programming to select the initial digit from 7 to 9, generate five more random digits, add a dash, and then append three random uppercase letters using alphanumeric ASCII codes.

Step-by-step explanation:

To generate a random password that begins with 7, 8, or 9, followed by any five digits ranging from 0 to 9, a dash, and then ends with three random uppercase letters, one can utilize programming languages such as Python, Java, or C++. Here's an example of how you might write such a program in Python:

import random
import string

def generate_password():
first_digit = str(random.choice([7, 8, 9]))
next_five_digits = ''.join(random.choices(string.digits, k=5))
three_letters = ''.join(random.choices(string.ascii_uppercase, k=3))
return first_digit + next_five_digits + '-' + three_letters

# Example usage:
print(generate_password())

This code snippet uses the random module to select the first digit and the subsequent five digits, as well as for selecting the three random uppercase letters by making use of the ASCII table, where the uppercase letters are represented by numbers from 65 to 90.
