An array is a sequential collection of elements of same data type and stores data elements in a continuous memory location. The elements of an array are accessed by using an index. The index of an array of size N can range from 0 to N−1. For example, if your array size is 5, then your index will range from 0 to 4 (5-1). Each element of an array can be accessed by using arr[index].
