What is array in c#?

Array is a collection of same type variable which stored in contiguous memory location. It means if you have to define 10 integer variables for different task, you can initialize an integer array with 10 elements. Element represents a single block of array. It will not only make your program simple but gives you better way to work with C#. An array element can be accessed by its index number.
