2D Matrix Modification 001

                    2D Matrix Modification

A Matrix has R rows and C columns. Get the matrix as input and multiply the value in the cells of the matrix by a value E if it is even and multiply it by a value F if it is odd.

Input Format:
The first line contains R.
The second line contains C.
Next R lines containing the elements of the matrix with each column value seperated by a space.
R+3 line contains E.
R+4 line contains F.

Output Format:
R lines containing the elements of the revised matrix with each column value seperated by a space.

Boundary Conditions:
1 <= R <= 100
1 <= C <= 100
1 <= E,F <= 100

Code:

#include <iostream>
using namespace std;
int main(int argc, char** argv)
{
    int i,j,r,c,e,f;
    cin>>r>>c;
    int arr[r][c];
    for(i=0;i<r;i++)
            for(j=0;j<c;j++)
                cin>>arr[i][j];
    cin>>e>>f;
    for(i=0;i<r;i++)
    {
        for(j=0;j<c;j++)
            {
             if(arr[i][j]%2==0)
                cout<<arr[i][j]*e<<" ";
            else
                cout<<arr[i][j]*f<<" ";
            }
        cout<<"\n";
    }
