Creating a 2D array with user input

December 5, 2021

I am trying to make a 2D array where user inputs the number of elements that array can take, also the elements inside the array. I think I manage to create the array, but when I try to put some elements inside it, for example 2×2 array and putting 2 as all of its elements i get this as the output. Here is the code:

#include<iostream>
#include<stdio.h>
using namespace std;
int main()
{
    int rowCount,colCount;
    cout<<"Enter the number of rows in Grid-Land:";
    cin>>rowCount;
    cout<<"Enter the number of columns in Grid-Land:";
    cin>>colCount;
    int** arr = new int*[rowCount];
    for(int i = 0; i < rowCount; ++i)
        arr[i] = new int[colCount];
    cout<<"Enter the garbage amounts at the nodes of the MxN Grid-Land:"<<endl;     //Elements of the array
    for(int i=0; i<rowCount; i++){
        for (int j=0; i<colCount; i++)
            cin>>arr[i][j];
    }   
    cout<<"\nThe 2-D Array is:\n";
    for(int i=0;i<rowCount;i++){
        for(int j=0;j<colCount;j++){
            cout<<"\t"<<arr[i][j];
        }
        cout<<endl;
      } 
    return 0;
}
