Array is a collection or group of elements(data).
All the elements of the C array are homogeneous(same data type).
It has a contiguous memory location.
Advantages of using Arrays:
Code Optimization
Easy to traverse data
Easy to sort data
Random Access
Disadvantage:
Declaration of Array:
data_type array_name[size];
Example: int num[5];
This will create an array of integer data type with array name as num of size 5.
Initialization of Array:
A simple way to initialize an array is by its index.
Array index starts from 0 and ends with [size-1].
Example:
marks[0]=80; //initialization of array
marks[1]=60;
marks[2]=70;
marks[3]=85;
marks[4]=75;
