# Write a C program to check Sparse Matrix

*Check Sparse matrix*

Write a C Program to Check a Matrix is Sparse Matrix or Not. Here’s simple Program to Check a Matrix is Sparse Matrix or Not in C Programming Language.

*What is Matrix ?*

**Matrix representation** is a method used by a computer language to store matrices of more than one dimension in memory. C uses “Row Major”, which stores all the elements for a given row contiguously in memory.

*Two-dimensional Arrays : :*

The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. An m × n (read as m by n) order matrix is a set of numbers arranged in m rows and n columns.

To declare a two-dimensional integer array of size [x][y], you would write something as follows −

*type arrayName [ x ][ y ];*

Where **type** can be any valid C data type and **arrayName** will be a valid C identifier.

Below is the source code for C Program to Check a Matrix is Sparse Matrix or Not which is successfully compiled and run on Windows System to produce desired output as shown below :

**SOURCE CODE : :**

**SOURCE CODE : :**

/* C Program to Check a Matrix is Sparse Matrix or Not */ #include <stdio.h> int main() { int A[10][10],i,j,m,n; int row, col, total = 0; printf("Enter no. of rows :: "); scanf("%d", &m); printf("\nEnter no. of cols :: "); scanf("%d",&n); printf("\nEnter values to the matrix :: \n"); for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { printf("\nEnter a[%d][%d] value :: ",i,j); scanf("%d", &A[i][j]); } } /* * Counts total number of zero elements in the matrix */ for(row=0; row<m; row++) { for(col=0; col<n; col++) { /* * If the current element is zero */ if(A[row][col] == 0) { total++; } } } if(total >= (row * col)/2) { printf("\nThe given matrix is a Sparse matrix."); } else { printf("\nThe given matrix is not Sparse matrix."); } return 0; }

*Output : :*

*Output : :*

/* C Program to Check a Matrix is Sparse Matrix or Not */ Enter no. of rows :: 3 Enter no. of cols :: 3 Enter values to the matrix :: Enter a[0][0] value :: 1 Enter a[0][1] value :: 0 Enter a[0][2] value :: 1 Enter a[1][0] value :: 1 Enter a[1][1] value :: 0 Enter a[1][2] value :: 0 Enter a[2][0] value :: 0 Enter a[2][1] value :: 1 Enter a[2][2] value :: 0 The given matrix is a Sparse matrix. Process returned 0
