hi @sy7176442_ca8a8991a7ddc322

#include <iostream>
using namespace std;
int main() {
    int n,m;
    cin>>n>>m; // n is no of rows and m is no of columns
    int arr[n][m]; //decalring a 2D array of size n*m
    for(int i=0;i<n;i++){ //reading input from user
        for(int j=0;j<m;j++){
            cin>>arr[i][j];
        }
    }

    for(int i=0;i<n;i++){ //printing the 2D array
        for(int j=0;j<m;j++){
            cout<<arr[i][j]<<" ";
        }
        cout<<endl;
    }
