How data structure helps in programming?

DATA STRUCTURES AS ITS NAME IMPLIES DATA MEANS "VALUE' AND STRUCTURE MEANS THE WAY IT IS ORGANISED AND THE WAY IT IS ARRANGED INTO MATHEMATICAL AND LOGICAL WAY.

Just like array...array helps you to store elements without declaring multiples variable

eg: num[100] can store 100 variables which are integers. Here if you are not using array and want to store data in 100 variables then you must declare 100 unique variables names. This can be done effectively using data structures.
