    Define 'large'.

    That depends entirely upon your compiler and platform.

    Again this depends upon your compiler, and also upon the
    context in which they're used. Some might be stored in
    your program's image, some might become 'immediate' operands
    of machine instructions.

    None of what you ask is addressed by the language, so
    we cannot answer conclusively.

    Consult your compiler documentation, and/or search your
    compiler's support resources.
