In this tutorial, i am going to show you how to find sum of each row in a matrix in c programs.
C Program to Find Sum each row in a Matrix
/* C Program to find Sum of rows 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[rows][columns];
}
printf("The Sum of Elements of a Rows in a Matrix = %d \n", Sum );
}
return 0;
}
The result 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 Elements of a Rows in a Matrix = 6 The Sum of Elements of a Rows in a Matrix = 15 The Sum of Elements of a Rows in a Matrix = 24
C Program to Find Sum each row in a Matrix using Function
/* C Program to find Sum of rows in a Matrix */
#include<stdio.h>
void addRows(int arr[10][10], int i, int j)
{
int rows, columns;
for(rows = 0; rows < i; rows++)
{
int Sum = 0;
for(columns = 0; columns < j; columns++)
{
Sum = Sum + arr[rows][columns];
}
printf("The Sum of Elements of a Rows 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]);
}
}
addRows(a, i, j);
return 0;
}
The result 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 Elements of a Rows in a Matrix = 6 The Sum of Elements of a Rows in a Matrix = 15 The Sum of Elements of a Rows in a Matrix = 24
