C++ में Pointers, Pointer to an objects, Pointer to an Array की संपूर्ण जानकारी हिंदी में

#include<iostream> 
using namespace std;
int main() 
{
  int myNum = 10;
//Declaration of a pointer variable
     int* ptr; 
//Assigning a variable's address to a pointer 'ptr'
     ptr = &myNum;
//Printing everything 
  cout << "Value of myNum: " << myNum << endl;
  cout << "Address of myNum: " << &myNum << endl;
  cout << "Value at ptr: " << ptr << endl;
  cout << "Value at *ptr: " << *ptr << endl;
  return 0;
}

#include<iostream>

using namespace std; 
class Book

public:

#include<iostream>
using namespace std;
int main()
 {
    int myArr[5] = {23, 10, 40, 22, 34};  // Initialize array
    int* ptr = myArr;   // Pointer to the array

    // Print array elements using pointer
    for (int i = 0; i < 5; i++) 
   {
        cout << *(ptr + i) << " ";
    }
    cout << endl;
    return 0;
}
Output:

23 10 40 22 34
