Compiling...
Imagine you need to write a program that stores the final exam marks of 100 students. Using what we've learned so far, you would have to declare 100 individual variables (int marks1, marks2, marks3...). That is highly inefficient!
To solve this, C provides Arrays. An array is a collection of variables of the same data type, stored in contiguous (side-by-side) memory locations, and accessed using a single shared name.
