Question

Consider the following function:
void func (int * ptr);
Suppose in main(), the above function is invoked:
func (x_ptr);
Which of the following statements is false?
The function could change the value pointed to by ptr
The function could change the memory address stored in ptr
O The function could change the value pointed to by x_ptr
The function could change the memory address stored in x_ptr
All of the above statements are actually true.

Suppose the class MyClass does not explicitly define a copy constructor. Assuming a
is an object of MyClass, what is the effect of the following line of code?
MyClass b = a;
%3D
O A shallow copy of a's data members will be given to b.
O A deep copy of a's data members will be given to b.
O The data members of b will be left uninitialized
O The data members of b will be default initialized (to 0, false, nullptr, etc.)
O That line of code would cause a syntax error.

(Perfect Numbers) An integer number is said to be a perfect number if its factors, including1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 =1 + 2 + 3. Write a function isPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect.Challenge the power of your computer by testing numbers much larger than 1000.
