## What is a palindrome number?

ONE **Palindromic number** or number **palindrome** is a **number** it stays the same if its digits are reversed. For example, like 16461, it is “symmetrical”. The term **palindrome** is derived from **palindrome**, which refers to a word (like rotor or racing car) whose spelling remains unchanged when its letters are reversed.

## What is an Armstrong number in C ++?

**C ++** Program to check **Armstrong number**. Posted by Chaitanya Singh | Filed under: **C ++** Programs. A whole number **number** is called **Armstrong number** if the sum of the cubes of its digits is equal **number** itself. For example: 370 is a **Armstrong number** because: 370 = 3 * 3 * 3 + 7 * 7 * 7 + 0 * 0 * 0 = 27 + 343 + 0 = 370.

## What is a neon number?
