Question

Suppose you are given Total mark of 50 students in a class 

1. How will you store these values using ordinary variable? 

2. Is there any other efficient way to store these values? Give reason.

Answer 1

We have to declare 50 variables individually to store total marks of 50 students. It is a laborious work. 

Hence we use array, it is an efficient way to declare 50 variables. With a single variable name we can store multiple elements.

eg: int mark[50]. 

Here we can store 50 marks. 

The first mark is in mark[0], second is in mark[1]…. etc the fiftieth mark is in mark[49],
