An array is an ordered collection of elements. Each element of the array is assigned a value. An array element can be considered as a variable. All the elements of the array are indexed. Zero and whole numbers are used as indices. Indexing of the array elements is purposeful. It helps to identify the array elements uniquely. An array-name is associated with each array. The array-name once tagged, comes to be associated with each array element. In other words, the array-name becomes part and parcel of the identity of all the array elements. In such a scenario, when the same array-name applies to each array element, the unique index of each element gives the required uniqueness. This uniqueness is acquired by each and every array element. In this way identification of the array elements is helped. In order words, uniqueness is bestowed upon the array elements with the help of indices. Distinctiveness of array elements helps in data processing. We are able to...
