In this tutorial, i am going to show you how to find sum of each and every row and column in a matrix in c programs.
C Program to Find Sum of each and every Row and Column in a Matrix
/* C Program to find Sum of each row and column of a Matrix */
#include<stdio.h>
int main()
{
int i, j, rows, columns, a[10][10], Sum;
printf("\n Please Enter Number of rows and columns : ");
scanf("%d %d", &i, &j);
printf("\n Please Enter the Matrix 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("\n The Sum of Elements of a Rows in a Matrix = %d", Sum );
}
for(rows = 0; rows < i; rows++)
{
Sum = 0;
for(columns = 0;columns < j; columns++)
{
Sum = Sum + a[columns][rows];
}
printf("\n The Sum of Elements of a Columns in a Matrix = %d", 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 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 The Sum of Elements of a Columns in a Matrix = 12 The Sum of Elements of a Columns in a Matrix = 15 The Sum of Elements of a Columns in a Matrix = 18
