Hello all,

I have a couple of questions reagarding the new keyword in C++. First, can someone tell exactly what is the difference between the following two code segments:

Account a = Account(35.00, 34234324); 
    Account *ptrA = &a;

Account *a = new Account("John", 10.50, 123456);

Secondly, Ive read that the following segment of code will lead to a memory leak after the b = a assignment is made. My question is, will the second segment of code also lead to a memory leak?


int main()
   Account *a = new Account("John", 10.50, 123456);  
   Account *b = new Account("Derek", 12.07, 123457);


   b = a;


int main()
    Account a = Account(35.00, 34234324); 
    Account *ptrA = &a; 1

    CurrentAccount b = CurrentAccount(50.0, 12345, 200.0);
    CurrentAccount *ptrB = &b; 2

    cout << "Displaying ptrA:" << endl;
    ptrA->display(); 3
    cout << "Displaying ptrB:" << endl;
    ptrB->display(); 4

    ptrA = ptrB; 6
    cout << "Displaying ptrA again:" << endl;
    ptrA->display();  7
