C Program to Find Sum of each column in a Matrix

C program to find sum each column in a matrix; Through this tutorial, we will learn how to find sum of each column in a matrix in c programs.

C Program to Find Sum of each column in a Matrix using For Loop

/* C Program to find Sum of columns in a Matrix  */

#include<stdio.h>

int main()
{
    int i, j, rows, columns, a[10][10], Sum;

    printf("Please Enter Number of rows and columns  :  ");
    scanf("%d %d", &i, &j);

    printf("Please Enter the Matrix Row and Column Elements \n");
    for(rows = 0; rows < i; rows++)
    {
        for(columns = 0; columns < j; columns++)
        {
            scanf("%d", &a[rows][columns]);
        }
    }

    for(rows = 0; rows < i; rows++)
    {
        Sum = 0;
        for(columns = 0; columns < j; columns++)
        {
            Sum = Sum + a[columns][rows];
        }
        printf("The Sum of Column Elements in a Matrix =  %d \n", Sum );
    }

    return 0;
}

The output of the above c program; as follows:

Please Enter Number of rows and columns  :  3 3
Please Enter the Matrix Row and Column Elements
1 2 3
4 5 6
7 8 9
The Sum of Column Elements in a Matrix =  12
The Sum of Column Elements in a Matrix =  15
The Sum of Column Elements in a Matrix =  18 

C Program to Find Sum of each column in a Matrix using Function

/* C Program to find Sum of columns in a Matrix  */

#include<stdio.h>

void AddColumns(int arr[10][10], int i, int j)
{
    int rows, columns, Sum = 0;
    for(columns = 0; columns < j; columns++)
    {
        for(rows = 0; rows < i; rows++)
        {
            Sum = Sum + arr[rows][columns];
        }
        printf("The Sum of Column Elements in a Matrix =  %d \n", Sum );
    }
}
int main()
{
    int i, j, rows, columns, a[10][10];

    printf("Please Enter Number of rows and columns  :  ");
    scanf("%d %d", &i, &j);

    printf("Please Enter the Matrix Row and Column Elements \n");
    for(rows = 0; rows < i; rows++)
    {
        for(columns = 0; columns < j; columns++)
        {
            scanf("%d", &a[rows][columns]);
        }
    }
    AddColumns(a, i, j);
    return 0;
}

The output of the above c program; as follows:

Please Enter Number of rows and columns  :  3 3
Please Enter the Matrix Row and Column Elements
9 8 7
6 5 4
3 2 1
The Sum of Column Elements in a Matrix =  18
The Sum of Column Elements in a Matrix =  33
The Sum of Column Elements in a Matrix =  45
