C# Sharp Exercises: Find the sum of rows an columns of a Matrix
C# Sharp Array: Exercise-25 with Solution
Write a program in C# Sharp to find the sum of rows an columns of a Matrix.
Sample Solution:-
C# Sharp Code:
using System;
public class Exercise25
{
public static void Main()
{
int i,j,n;
int[,] arr1 = new int[10,10];
int[] rsum = new int[10];
int[] csum = new int[10];
Console.Write("\n\nFind sum of row and column of a Matrix:\n ");
Console.Write("-------------------------------------------\n");
Console.Write("Input the size of the square matrix : ");
n = Convert.ToInt32(Console.ReadLine());
Console.Write("Input elements in the matrix :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
Console.Write("element - [{0}],[{1}] : ",i,j);
arr1[i,j]=Convert.ToInt32(Console.ReadLine());
}
}
Console.Write("The matrix is :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n ;j++)
Console.Write("{0} ",arr1[i,j]);
Console.Write("\n");
}
/* Sum of rows */
for(i=0;i<n;i++)
{
rsum[i]=0;
for(j=0;j<n;j++)
rsum[i]=rsum[i]+arr1[i,j];
}
/* Sum of Column */
for(i=0;i<n;i++)
{
csum[i]=0;
for(j=0;j<n;j++)
csum[i]=csum[i]+arr1[j,i];
}
Console.Write("The sum of row and column of the matrix :\n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
Console.Write("{0} ",arr1[i,j]);
Console.Write("{0} ",rsum[i]);
Console.Write("\n");
}
Console.Write("\n");
for(j=0;j<n;j++)
{
Console.Write("{0} ",csum[j]);
}
Console.Write("\n\n");
}
}
Sample Output:
Find sum of row and column of a Matrix: ------------------------------------------- Input the size of the square matrix : 2 Input elements in the matrix : element - [0],[0] : 2 element - [0],[1] : 4 element - [1],[0] : 6 element - [1],[1] : 8 The matrix is : 2 4 6 8 The sum of row and column of the matrix : 2 4 6 6 8 14 8 12
