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 Addition of two Matrices which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C Program for Addition of two matrices  */

#include <stdio.h>

int main()
{
    int A[10][10],B[10][10],C[10][10],i,j,m,n;
    int row, col;

    printf("Enter no. of rows :: ");
        scanf("%d", &m);
        printf("\nEnter no. of cols :: ");
        scanf("%d",&n);

        printf("\nEnter values to the matrix A :: \n");
        for (i = 0; i < m; i++)
        {
            for (j = 0; j < n; j++)
            {
                 printf("\nEnter a[%d][%d] value :: ",i,j);
                 scanf("%d", &A[i][j]);
        }
    }

    printf("\nThe given matrix A is :: \n\n");

        for (i = 0; i < m; ++i)
        {
            for (j = 0; j < n; ++j)
            {
                printf("\t%d", A[i][j]);
            }
            printf("\n\n");
        }

    printf("\nEnter values to the matrix B :: \n");
        for (i = 0; i < m; i++)
        {
            for (j = 0; j < n; j++)
            {
                 printf("\nEnter a[%d][%d] value :: ",i,j);
                 scanf("%d", &B[i][j]);
        }
    }

    printf("\nThe given matrix B is :: \n\n");

        for (i = 0; i < m; ++i)
        {
            for (j = 0; j < n; ++j)
            {
                printf("\t%d", B[i][j]);
            }
            printf("\n\n");
        }

    /*
     * Adds both matrices A and B entry wise or element wise
     * And stores result in matrix C
     */
    for(row=0; row<m; row++)
    {
        for(col=0; col<n; col++)
        {
            C[row][col] = A[row][col] + B[row][col];
        }
    }

    /*
     * Prints the Addition of two matrices A and B
     */
    printf("\nAddition of matrices A + B = C\n");
    printf("\nThe given matrix C is :: \n\n");

        for (i = 0; i < m; ++i)
        {
            for (j = 0; j < n; ++j)
            {
                printf("\t%d", C[i][j]);
            }
            printf("\n\n");
        }

    return 0;
}
