Detailed explanation-1: -An array can be of any data type, but can only hold a single data type. Specifically, you can declare an array that holds strings and an array that holds integers, but you cannot declare a single array that holds both strings AND integers.
Detailed explanation-2: -Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type i.e. 1. All elements of an array can be Integers.
