Arrays

An array is the most primitive and frequently used data structure in the field of computer science. It has become the inspiration for several data structures such as lists and strings. An array is basically a collection of similar types of data items stored at contiguous memory locations. It helps us to store multiple items of the same data type together. They are also used to implement other data structures like Heaps, Stacks, Queues, etc. This category contains all of the information you need to know about arrays.
