Question 15

The other way to initialize variables is
done by enclosing the initial value
between parentheses ().

Answer 15

constructor initialization

Question 16

3 places in a C++ program where variables can be declared:

Answer 16

1. outside of all functions
2. inside the functions
3. in the declaration of a formal parameter of a function.

Question 17

Outside of all functions, including the main() function

may be used by any part of the
program.

Answer 17

global

Question 18

Inside the function

may be used only by statements that are also in
the same function.

Answer 18

local
