Possible memory leak without a virtual destructor?

Question

#include 
using namespace std;
class base
{
   int a;
 public: 
   base() {a =0;}
 };
 class derv :public base
 {
   int b;
  public:
   derv() {b =1         


        

Answer 1

There is no memory leak in your code. There would have been a memory leak if you needed to free some memory in the derived class destructor.
