# C# Sharp Exercises: Determine whether a matrix is a sparse matrix

## C# Sharp Array: Exercise-29 with Solution

Write a program in C# Sharp to accept a matrix and determine whether it is a sparse matrix.

Sample Solution:-

C# Sharp Code:

``````/*A sparse martix is matrix which  has more zero elements than nonzero elements */
using System;
public class Exercise29
{
public static void Main()
{
int[,] arr1 = new int[10,10];
int i,j,r,c;
int ctr=0;

Console.Write("\n\nDetermine whether a matrix is a sparse matrix :\n ");
Console.Write("----------------------------------------------------\n");
Console.Write("Input the number of rows of the matrix : ");
Console.Write("Input the number of columns of the matrix : ");
Console.Write("Input elements in the first matrix :\n");
for(i=0;i<r;i++)
{
for(j=0;j<c;j++)
{
Console.Write("element - [{0}],[{1}] : ",i,j);
if (arr1[i,j]==0)
{
++ctr;
}
}
}
if (ctr>((r*c)/2))
{
Console.Write ("The given matrix is sparse matrix. \n");
}
else
Console.Write ("The given matrix is not a sparse matrix.\n");

Console.Write ("There are {0} number of zeros in the matrix.\n\n",ctr);

}
}
```
```

Sample Output:

```Determine whether a matrix is a sparse matrix :
----------------------------------------------------
Input the number of rows of the matrix : 2
Input the number of columns of the matrix : 2
Input elements in the first matrix :
element - [0],[0] : 0
element - [0],[1] : 1
element - [1],[0] : 0
element - [1],[1] : 0
The given matrix is sparse matrix.
There are 3 number of zeros in the matrix.
```
