C program to read m x n matrix and calculate the Row sum and Column sum of the matrix.

    In this example, we read a m x n matrix whose value would be entered by the user then the sum of row and column is calculated. Here in the example we have taken a matrix of order 3 x 2 whose row sum and column sum is displayed in the output screen.

PROGRAM TO READ m x n MATRIX AND CALCULATE THE ROW SUM AND COLUMN SUM OF THE MATRIX:

#include<stdio.h>

#include<conio.h>

void main()

{

    int i,j,m[100][100],row,column,rsum,csum=0;

    printf("Enter the row size of the matrix :");

    scanf("%d",&row);

    printf("Enter the column size of the matrix :");

    scanf("%d",&column);

    printf("Enter the Matrix : ");

    for(i=0;i<row;i++)

    {

        for(j=0;j<column;j++)

        {

            scanf("%d",&m[i][j]);

        }

    }

    for(i=0;i<row;i++)

    {

        rsum=0;

        for(j=0;j<column;j++)

        {

            rsum=rsum+m[i][j];

        }

        printf("\nSum of row %d : %d",i+1,rsum);

    }

    for(j=0;j<column;j++)

    {

        csum=0;

        for(i=0;i<row;i++)

        {

            csum=csum+m[i][j];

        }

        printf("\nSum of column %d : %d",j+1,csum);

    }

    getch();

}

OUTPUT  TO READ M X N MATRIX AND CALCULATE THE ROW SUM AND COLUMN SUM OF THE MATRIX:

    Enter the row size of the matrix :3

    Enter the column size of the matrix :2

    Enter the Matrix : 12

    34

    65

    7

    23

    9

    

    Sum of row 1 : 46    

    Sum of row 2 : 72    

    Sum of row 3 : 32    

    Sum of column 1 : 100

    Sum of column 2 : 50
