Question

1. Write TWO different but equivalent statements to do the same thing: use a for statement to print the elements of array numbers by using pointer ptr.

2. Write an expression that uses ptr to copy element 1 (zero-based) of the array to element 3. Do not use numbers in the array in

Here is the start of a class declaration:
class foo
{
public:
void x(foo f);
void y(const foo f);
void z(foo f) const;
...
3. Which of the three member functions can alter the PRIVATE member variables of the foo object that activates the function?

a. All of the functions can alter the private member variables of the object that activates the function.

b. Only z can alter the private member variables of the object that activates the function.

c. Only x can alter the private member variables of the object that activates the function.

d. Only y can alter the private member variables of the object that activates the function.

Two of the functions can alter the private member variables of the object that activates the function.

Answer 1

1)
answer:
statement1:
for(int i=0;i<n;i++)//assuming length of the array is n
cout<<*(ptr+i);
statement2:
for(int i=0;i<n;i++)//assuming length of the array is n
cout<<ptr[i];

2)
answer:
ptr[2]=ptr[0];//copying element1 of array to element3

3)
Answer:
functions x and y can alter the private member variables of the object that activates the function.
