int* arr = new int[size];

Or, more specifically:

#include<iostream>

using namespace std;

int main()
{
    int s;
    cout << "Enter the size";
    cin>>s;
    
    int* arr = new int[s];//according to notes here will be error becz of
    
    return 0;
}

You can use that const int size if you want, don't have to, depends on your style/program.

Deepak, I've asked you before to use the code tags please. If you don't know how then communicate. I'll be glad (or anyone else) to assist you in using these tags.

See an example below my name... above the picture.
