Explanation: Array in simple sense refers to a collection of similar data. It holds data which is homogeneous in nature, meaning they are all alike. The use of array provide a lot of advantages in the fields of computer programming. When you declare a variable for an array, you can store as much data as you wish in the same variable without having to declare many variables.
