I dont know about 1800 words but I sure can tell you abit about array
Explanation: Array in simple sense refers to a collection of similar data. It holds data which is homogeneous in nature, meaning they are all alike. The use of array provide a lot of advantages in the fields of computer programming. When you declare a variable for an array, you can store as much data as you wish in the same variable without having to declare many variables. A 2X2 dimensional array can also be used in programming which represents matrices as well. The search process in an array too is really convenient and time saving. Also in an array, accessing an element is very easy by using the index number.
