Q: What will happen in the following code after the function foo() returns?
class base
{
public:
base() { }
~base() { }
};
class derived : public base
{
private:
int *p_pi_values;
public:
derived() : p_pi_values(new int[100]) { }
~derived() { delete [] p_pi_values; }
};
void foo(void)
{
derived *p_derived = new derived();
base *p_base = p_derived;
// Do some other stuff here.
delete p_base;
}
class base
{
public:
base() { }
~base() { }
};
class derived : public base
{
private:
int *p_pi_values;
public:
derived() : p_pi_values(new int[100]) { }
~derived() { delete [] p_pi_values; }
};
void foo(void)
{
derived *p_derived = new derived();
base *p_base = p_derived;
// Do some other stuff here.
delete p_base;
}
