For a better understanding, we always recommend you to learn the basic topics of C programming listed below:

In this program, we need to check whether the given matrix is the sparse matrix. A sparse matrix is a matrix that has more zero elements than non-zero elements; it is used to store the elements with a large number of zero elements. An example of a sparse matrix is shown below.

**A=
5 0 0
0 4 0
3 0 0**

Here the matrix a has **6** zero elements and three non-zero elements so that we can call the matrix a **sparse matrix**.

In this example, so we need to check how many zeros and non-zeros elements are there in a matrix. So we accept a matrix, and we start a `for loop`

to check each element of the matrix, then we use a counter and increment that counter every time we meet a zero element. Now we check the counter is greater than '**[m*n]/2**'; if it is correct, we print it as a sparse matrix. Else we print not a sparse matrix. It is a simple matrix c program.

STEP 1: Include the header files to use the built-in Functions in the C program.

STEP 2: Declare the variable **i,j,m,n,counter,m1[10][10] **as integer .

STEP 3: Read the order of the Matrix from the user into the variables **m **and **n**.

STEP 4: Read the coefficients of the Matrix by using `for loop`

into the matrix **m1[i[j]**.

STEP 5: Check **m1[i][j]=0** ,if true then increment the counter by **1** and repeat step 4.

STEP 6: Check `if`

**counter>(m*n)/2**, then display the given Matrix as a sparse matrix. `Else`

do step 7.

STEP 7: Else display the given Matrix is not a sparse matrix.

STEP 8: Display There is a **counter **number of zeros by using the `printf`

function.

` ````
#include <stdio.h>
void main()
{
static int m1[10][10];
int i, j, m, n;
int counter = 0;
printf("Enter the order of the matix\n");
scanf("%d %d", & m, & n);
printf("Enter the coefficients of the matix\n");
for (i = 0; i < m; ++i)
{
for (j = 0; j < n; ++j)
{
scanf("%d", & m1[i][j]);
if (m1[i][j] == 0)
{
++counter;
}
}
}
if (counter > ((m * n) / 2))
{
printf("The given matrix is a sparse matrix \n");
} else
printf("The given matrix is not a sparse matrix \n");
printf("There are %d number of zeros", counter);
} /* EN dof main() */ /*end of main() */
```

Enter the order of the matrix 2*2 Enter the coefficients of the matrix 1 2 3 4 The given matrix is not a sparse matrix There are 0 number of zeros Run 2 Enter the order of the matrix 3*3 Enter the co-efficiency of the matrix 1 0 0 0 0 1 0 1 0 The given matrix is a sparse matrix There are 6 number of zeros
