Program to Check if it is a Sparse Matrix

Program to Check if it is a Sparse Matrix

This is a C++ Program to check sparsity of a given matrix. If the number of zeros in a matrix exceeds (n*m)/2, where n, m is the dimension of the matrix, matrix is sparse matrix.

    #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<m; i++)

        {

            for(int j=0; j<n; 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";

        }

    }

C Print Elements of Array using Recursion - Define our Recursive Function to print array elements & say printArray(int arr[], int start, int len). The function takes three parameters where first is array to print, second is starting

C++ Sample Passing Pointers to Functions - "In C++", each 'parameter' was followed by an "ampersand sign" (&). (&) will pass an address of the original variable instead of by value. In Passed by reference, the original variable and

Weakly Connected or Strongly Connected - Program to find the connected components of the "Undirected Graph". This can be done using depth first search algorithm. Fills stack with vertices (in increasing order of finishing

Program to check Palindrome string using - A 'Palindrome' is a special string which reads same from backward or forward such as eye, mom, madam, dad, bob, teet. We traverse a string character by character 'both direction'

C++ Coding Find Factorial using recursion - User enters a number which stores in variable "num". Then number "passes as argument" in function call A static variable is used to check that how many times function is called. When

The C Language Print the Floyd's Triangle - Floyd's triangle, named after 'Rober Floyd', is a Right Angled Triangle, which is made using natural numbers. Starts from 1, consecutively selects the next Greater number in Sequence.

C++ Performing Edge Coloring of a Graph - In graph theory, an "edge coloring" of a graph is an assignment of colors to the edges of the graph so that no two adjacent edges have the same color. Any "2 edges" connected to same

C Data Structures Dynamic String Arrays - Dynamic string arrays in C language. Print the array of strings. Free the string array, Note: You must delete each individual string before you delete the array of pointers...
