C++ Program to Check if it is a Sparse Matrix


Code:

#include     iostream
#include     conio.h

using namespace std;
int main(int argc, char **argv)
{
    cout<<"Enter the dimensions of the matrix: ";
    int m, n;
    cin>>m>>n;
    double mat[m][n];
    int zeros = 0;
    cout<<"Enter the elements of the matrix: ";
    for(int i=0; i
    {
        for(int j=0; j
        {
            cin>>mat[i][j];
            if(mat[i][j] == 0)
            {
                zeros++;
            }
        }
    }

    if(zeros > (m*n)/2)
    {
        cout<<"The matrix is a sparse matrix";
    }
    else
    {
        cout<<"The matrix is not a sparse matrix";
    }

}


Output:

Enter the dimensions of the matrix: 
3 3

Enter the elements of the matrix: 
1 2 3
4 5 6
0 0 0

The matrix is not a sparse matrix


Enter the dimensions of the matrix: 
3 3

Enter the elements of the matrix: 
1 1 0
0 0 1
1 0 0

The matrix is a sparse matrix
