Detailed explanation-1: -In computer science, array is a data type that represents a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time during program execution. Such a collection is usually called an array variable or array value.
Detailed explanation-2: -A variable of array type holds a reference to an object. Declaring a variable of array type does not create an array object or allocate any space for array components. It creates only the variable itself, which can contain a reference to an array.
Detailed explanation-3: -An array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. Depending on the language, array types may overlap (or be identified with) other data types that describe aggregates of values, such as lists and strings.
Detailed explanation-4: -An array variable is a two-dimensional variable that holds multiple values in a table of rows and columns. Arrays are very powerful for creating staging areas for data that need to be retrieved by your process as it runs.
