Add Two Matrices using array


Write a C++ Program to Add Two Matrices using array. Here’s simple Program to Add Two Matrices using array in C++ Programming Language.


What is Matrix ?


Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory. C uses “Row Major”, which stores all the elements for a given row contiguously in memory.

Two-dimensional Arrays : :

The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. An m × n (read as m by n) order matrix is a set of numbers arranged in m rows and n columns.

To declare a two-dimensional integer array of size [x][y], you would write something as follows −

  • type arrayName [ x ][ y ];

Where type can be any valid C data type and arrayName will be a valid C identifier.


Below is the source code for C++ Program to Add Two Matrices using array which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C++ Program to Add Two Matrices using array  */

#include<iostream>
using namespace std;

int main()
{

        int arr1[5][5], arr2[5][5], arr3[5][5], sub, i, j,m,n;

    cout<<"Enter size of matrix ( Max:5 ) :: ";
    cin>>m;
    cout<<"\nEnter Elements to Matrix A Below :: \n";

    for(i=0;i<m;i++)
    {
        for(j=0;j<m;++j)
        {
            cout<<"\nEnter arr1["<<i<<"]["<<j<<"] Element :: ";
            cin>>arr1[i][j];
        }

    }

    cout<<"\nEnter Elements to Matrix B Below :: \n";

    for(i=0;i<m;i++)
    {
        for(j=0;j<m;++j)
        {
            cout<<"\nEnter arr2["<<i<<"]["<<j<<"] Element :: ";
            cin>>arr2[i][j];
        }

    }


        cout<<"\nAdding Matrix ( A + B ) ..... \n";
        for(i=0; i<m; i++)
        {
                for(j=0; j<m; j++)
                {
                        arr3[i][j]=arr1[i][j]+arr2[i][j];
                }
        }

        cout<<"\nAfter Addition, Matrix C is :: \n";

        for (i = 0; i < m; ++i)
        {
            for (j = 0; j < m; ++j)
            {
                cout<<"\t"<<arr3[i][j];
            }
            printf("\n\n");
        }

        return 0;
}

OUTPUT : :


/*  C++ Program to Add Two Matrices using array  */

Enter size of matrix ( Max:5 ) :: 3

Enter Elements to Matrix A Below ::

Enter arr1[0][0] Element :: 1

Enter arr1[0][1] Element :: 2

Enter arr1[0][2] Element :: 3

Enter arr1[1][0] Element :: 4

Enter arr1[1][1] Element :: 5

Enter arr1[1][2] Element :: 6

Enter arr1[2][0] Element :: 7

Enter arr1[2][1] Element :: 8

Enter arr1[2][2] Element :: 9

Enter Elements to Matrix B Below ::

Enter arr2[0][0] Element :: 1

Enter arr2[0][1] Element :: 2

Enter arr2[0][2] Element :: 3

Enter arr2[1][0] Element :: 4

Enter arr2[1][1] Element :: 5

Enter arr2[1][2] Element :: 6

Enter arr2[2][0] Element :: 7

Enter arr2[2][1] Element :: 8

Enter arr2[2][2] Element :: 9

Adding Matrix ( A + B ) .....

After Addition, Matrix C is ::
        2       4       6

        8       10      12

        14      16      18


Process returned 0
