Question

The _____ operator is used to release the amount of memory that was dynamically created using the _____ operator

T/F A constant pointer implies a pointer to a constant variable.

T/F Once a constant pointer is initialized with an address, it cannot point to anything else.

T/F Though a function can accept pointer variables as arguments, a function can never return a pointer.

T/F A smart pointer can automatically delete a dynamically allocated memory when it is not in use anymore, without the need of the delete operator to be explicitly called to do so.

Answer 1

1. The delete operator is used to release the amount of memory that was dynamically created using the new operator.

2. A constant pointer implies a pointer to a constant variable: False

A constant pointer is a pointer that cannot change its own value. i.e. It cannot point to some other variable.

3. Once a constant pointer is initialized with an address, it cannot point to anything else: True

4. Though a function can accept pointer variables as arguments, a function can never return a pointer: False

We can return a pointer through a function. To avoid error we should not return a pointer which points to a local variable in the function.

5. A smart pointer can automatically delete a dynamically allocated memory when it is not in use anymore, without the need of the delete operator to be explicitly called to do so. : True
