# Write an application to check a number is even or odd.

Solution)

Numbers which are divisible by 2 are even numbers whereas the numbers which are **not **divisible by 2 are odd numbers.

**Example:**

2, 6, 8, 12, 20 are some examples of even numbers. These numbers are divisible by 2.

3, 5, 7, 11, 15 are some examples of odd numbers. These numbers are **not** divisible by 2.

Even number of objects can be grouped in pairs whereas odd number of objects can **not **be grouped in pairs.

In order to find whether a number is an even number or odd number, divide the number by 2. If the remainder obtained on dividing the number by 2 is 0, then the number is an even number otherwise it is an odd number.

So, numbers end with 0, 2, 4, 6, 8 are divisible by 2 and numbers end with 1, 3, 5, 7, 9 are not divisible by 2 are odd numbers.

Hence, this method helps to find whether a number is odd or even regardless of how many digits it has by looking at final digit.
