How to generate sparse matrix in c?

``````

/* program to generate sparse matrix*/
#include

void main ()
{
static int array[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 co-efficients of the matix \n");
for (i = 0; i < m; ++i)
{
for (j = 0; j < n; ++j)
{
scanf("%d", &array[i][j]);
if (array[i][j] == 0)
{
++counter;
}
}
}
if (counter > ((m * n) / 2))
{
printf("The given matrix is sparse matrix \n");
}
else
printf("The given matrix is not a sparse matrix \n");
printf("There are %d number of zeros", counter);
}``````
out put:
Enter the order of the matix
3 3
Enter the co-efficients of the matix
10 20 30
5 10 15
3 6 9
The given matrix is not a sparse matrix
There are 0 number of zeros

\$ a.out
Enter the order of the matix
3 3
Enter the co-efficients of the matix
5 0 0
0 0 5
0 5 0
The given matrix is sparse matrix
There are 6 number of zeros
