Question & Answer: Writing a program that if an element in an m*n matrix is 0, it's entire row and column is set to 0……

#include<iostream>
#include<memory.h>
#include<cstdlib>
using namespace std;

void SetZeros(int** matrix,int m,int n)
{
int row[m];
int column[n];
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
if(*((int*)matrix+n*i+j)==0)
{
row[i]=1;
column[j]=1;
}
}
}
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
if(row[i]==1 || column[j]==1)
{
*((int*)matrix+n*i+j)=0;
}
}
}
}

void fillArray(int** matrix,int m,int n)
{
cout<<“Enter Data in Array “<<endl;
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
cout<<“Enter element [“<<i<<“][“<<j<<“]: “<<endl;
cin>>*((int*)matrix+n*i+j);
}
}
}

void printArray(int** matrix,int m,int n)
{
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
cout<<*((int*)matrix+n*i+j)<<” “;
}
cout<<endl;
}
}

int main()
{
int m;
int n;
cout<<“please enter number of rows: “<<endl;
cin>>m;
cout<<“Please enter the number of columns: “<<endl;
cin>>n;
int matrix[m][n];
fillArray((int**)matrix,m,n);
cout<<“nEntered Matrix is: “<<endl;
printArray((int**)matrix,m,n);

SetZeros((int**)matrix,m,n);
cout<<“The answer is: “<<endl;
printArray((int**)matrix,m,n);
return 0;
}
