C++ Program to Reverse an Array using functions

What is an Array ?

Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

Here is source code of the C++ Program to Reverse an Array using functions. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

SOURCE CODE : :

/*  C++ Program to Reverse an Array using functions  */

#include <iostream>
using namespace std;

void Reverse_Array(int array[],int size);

int main()
{
        int i,a[50],size;
    cout<<"Enter array size( Max:50 ) :: ";
    cin>>size;
        cout<<"\nEnter array elements :: \n";

        for(i=0; i<size; i++)
        {
            cout<<"\nEnter arr["<<i<<"] Element :: ";
                cin>>a[i];
        }

  cout<<"\nStored Data in Array :: \n\n";

  for(i=0;i<size;i++)
  {
  cout<<" "<<a[i]<<" ";
  }
        // Calling Reverse Array Values Function
        Reverse_Array(a,size);
        cout << "\n\nReversed Array Values are :: " << endl;
    for(i=0;i<size;i++)
    {
      cout<<" "<<a[i]<<" ";
    }

    cout<<"\n";

        return 0;
}

//------Reverse Array Function---------------

void Reverse_Array(int array[],int size)
{
        int temp;
        size--;
        for (int i=0;size>=i;size--,i++)
    {
                temp=array[i];
                array[i]=array[size];
                array[size]=temp;
        }
}

OUTPUT : :

/*  C++ Program to Reverse an Array using functions  */

Enter array size( Max:50 ) :: 8

Enter array elements ::

Enter arr[0] Element :: 1

Enter arr[1] Element :: 2

Enter arr[2] Element :: 3

Enter arr[3] Element :: 4

Enter arr[4] Element :: 5

Enter arr[5] Element :: 6

Enter arr[6] Element :: 7

Enter arr[7] Element :: 8

Stored Data in Array ::

 1  2  3  4  5  6  7  8

Reversed Array Values are ::
 8  7  6  5  4  3  2  1

Process returned 0
