Which of the following file types is commonly used by digital cameras to store digital pictures in an efficient file size?

Why does the compiler complain if I attempt to use a vector as a base container for a stack of double values?

The declaration is: stack> myStack; The VC++ compiler says stack> myStack; //error: missing ',' //before identifier 'myStack'

What kind of iterators does the queue template container have?

What will be an ideal response?
