Answer 2

Problem Analysis

The problem requires finding the next even number after a given integer without using an `if` statement. We can solve this problem by using mathematical operations and the modulus operator.

Solution

To find the next even number after a given integer `a`, we can add 2 to `a` and then round it up to the nearest even number. Here's the solution in Python:

import math

a = int(input("Enter an integer: "))
next_even = math.ceil(a / 2) * 2

print("The next even number after", a, "is", next_even)

Let
