C++ pointers are

• Memory locations

• always int data type

• objects that do not require data type

• Variables that point at other variables

C++ Pointer variables contain

• Integer values

• addresses of locations in memory

• hexadecimal numbers

• None of the above

In C++ the heap is

• A special C++ library that controls the memory

• A special variable

• An amorphous block of memory that your program can access as necessary.

• An perfect block of memory that your program can access as necessary.

In C++ the Memory is broken into individual bytes with each byte carrying it’s own:

• Values

• Pointers

• Scope

• Address

The heap is:

• Symmetric storage

• a special variable

• A block of memory that is controlled by the programmer

• A block of memory that is controlled by the compiler

What are 2 typical problems with fixed array sizes?.

• Exceeding the maximum

• Use of For Loops

• Use of indexes to access the array

• No expansion

What do you use the "new" command in C++ for?.

• Create new object

• De-reference memory locations

• Allocate heap memory

• Create arrays

What does this command do?.

• Creates a pointer of type integer that is initially pointing to null.

• Creates a pointer of type integer that is initially pointing to 0.

• Creates a pointer in the heap

• None of the answers are valid

In C++ what the following command does: delete [ ] a;

• Nothing

• Creates a new array names a of type delete.

• Deletes a variable

• Free memory allocated for the a array

Do you have to reset a pointer after delete?.

• Yes

• No
