Hi

I have tried this below code

#include<iostream>
using namespace std;

int main()
{
int m,n;
cout<<"Enter the size of array ";
cin>>m>>n;
int arr[m][n];
int i,j;
cout<<"Enter the array element: "<<endl;
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
cout<<"Enter the "<<i+1<<j+1<<" element: ";
cin>>arr[i][j];
}
}
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
cout<<arr[i][j]<<" ";
}
cout<<endl;
}
return 0;
}
