Array

ARRAY

• An array is a collection of finite number of elements of similar data type in contiguous memory.
• All the elements are stored under same name.
• It can be of any data-type.

The above image is an array. Each of them can be differentiate by their indexes.

• Array always start from index 0.
• To access data at any point in array just type array_name[index]

Here is a Simple Code to Declare and Initialise an array of integer type in C++.

#include<iostream.h>
using namespcae std;
int main()
{
          int arr[5];    //Declaration of an Array arr of int type.
          int i;
          cout<<"\n Enter the elements of the array : ";
         //Initialising Array
         for(i=0;i<5;i++)
         {
                   cin>>arr[i];
         }
         //Displaying Array
         for(i=0;i<5;i++)
         {
                   cout<<arr[i];
         }
          return 0;
}
