Accessing Array Elements

162.7k

The advantages of using an array are:

  • The size of the array is fixed when you create it, so there's no need to worry about running out of space while storing data
  • Arrays are fast because they're stored in contiguous memory locations, so it takes less time to find the value that you're looking for
  • You can retrieve values from arrays very quickly by using their index number

array are stored in sequential order and it is possible to access any element by specifying its index. So, if we have an array of 5 elements, then the indexes will be from 0-4.

The first way to access an element in an array is by using its index. The second way to access an element in an array is by using its location in the array.

The C programming language uses the pointer operator * to access array elements. This is a mistake. C does not have a pointer operator.
