Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each

Yes, you're correct. Arrays are a type 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.

Here are the steps to declare an array in some programming languages:

1. JavaScript:

let arrayName = [item1, item2, ...];

2. Python:

arrayName = [item1, item2, ...]

3. Java:

dataType[] arrayName; //declaration
arrayName = new dataType[size]; //initialization

or

dataType[] arrayName = new dataType[size]; //both at the same time

4. C++:

dataType arrayName[arraySize];

In all these examples, dataType is the type of elements in the array, arrayName is the name of the array, size is the number of elements in the array, and item1, item2, ... are the elements.
