Answer 2

Problem Description

You need to write a program that prompts the user to enter three school numbers from the keyboard. The program should then check if your school number is among them. If it is, the program should display the message "Your school number is present." Otherwise, it should display the message "Your school number is not present."

Solution

Here's a possible solution in Python:

# Prompt the user to enter three school numbers
school_numbers = []
for i in range(3):
    school_number = input("Enter a school number: ")
    school_numbers.append(school_number)

# Check if your school number is present
your_school_number = "YOUR_SCHOOL_NUMBER"  # Replace with your actual school number
if your_school_number in school_numbers:
    print("Your school number is present.")
else:
    print("Your school number is not present.")

Make sure to replace `"YOUR_SCHOOL_NUMBER"` with your actual school number. This code prompts the user to enter three school numbers and stores them in a list called `school_numbers`. Then, it checks if your school number is present in the list using the `in` operator. If it is, it prints the message "Your school number is present." Otherwise, it prints the message "Your school number is not present."

Please note that this solution assumes you are using Python as the programming language. If you are using a different programming language, let me know and I can provide a solution in that language as well.
