# Problem 2: Write a Python program that prompts the user to input an integer and raises a ValueError exception if the
# input is not a valid integer.

# Define the function int_check to check if user input is an integer
def int_check(x):
    # Cast user input as integer, throws ValueError if not
    x = int(x)

# Call the function, prompting the user to input an integer
int_check(x = input('Enter an integer: '))
