2) Answer the question with the correct options given below
A)What is the output of the following code?
int *p1, *p2;
p1 = new int;
p2 = new int;
*p1 = 11;
*p2 = 0;
p2 = p1;
cout << *p1 <<" " << *p2 << endl;
- 0 11
- 11 0
- 0 0
- 11 11
B) What is wrong with the following code fragment?
int *p1, *p2;
p1 = new int;
p2 = new int;
*p1=11;
*p2=0;
p2=p1;
cout << *p1 <<" " << *p2 << endl;
delete p1;
delete p2;
- p1 and p2 both have the same value, so the delete p2 will cause an error
- nothing
- B and C
- You have a memory leak
C) Which of the following correctly declares a dynamic array of strings?
- p1 = new string[];
- p1 = new string[13];
- p1 = new string(13);
- p1 = new stringArray(13);
