pre-test

The while loop is this type of loop.

Literals

These are data items whose values do not change while the program is running.

++ and --

These are operators that add and subtract one from their operands.

prefix increment

This operator increments the value of its operand, then uses the value in context.

==

This operator is used in C++ to represent equality.

&&

This operator represents the logical AND.

return

This statement causes a function to end.

switch

This statement uses the value of a variable or expression to determine where the program will branch to.

local

This type of variable is defined inside a function and is not accessible outside the function.

subscript

To access an array element, use the array name and the element's ________.

cstdlib

To use the rand() function, you must #include this header file in your program.

arrays

Unlike regular variables, these can hold multiple values.

20,000

What does the following statement do? double *num2;

false

What is the value of the following expression? true && false

0

What is the value stored at x, given the statements: int x; x = 3 / static_cast<int>(4.5 + 6.4);
