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
