2.3.2.Get address of an int variable

#include <iostream> 

using namespace std; 

 

int main() 

{ 

  int total; 

  int *ptr; 

  int val; 

 

  total = 3200; // assign 3,200 to total 

 

  ptr = &total; // get address of total 

 

  val = *ptr;   // get value at that addres  

 

  cout << "Total is: " << val << '\n'; 

 

  return 0; 

}

Total is: 3200
