Which of the following is a reserved word in C++?

Suppose that alpha and beta are int variables. The statement alpha = beta++; is equivalent to the statement(s) ____.

____________________ functions are those that have already been written and are provided as part of the system.

If a C++ arithmetic expression has no parentheses, operators are evaluated from left to right.

The expression static_cast<int>(9.9) evaluates to ____.

____________________ is the process of planning and creating a program.

A(n) ____________________ is a collection of statements, and when it is activated, or executed, it accomplishes something.

Suppose that alpha and beta are int variables and alpha = 5 and beta = 10. After the statement alpha *= beta; executes, ____.

In C++, you can use a(n) ____________________ to instruct a program to mark those memory locations in which data is fixed throughout program execution.

A comma is also called a statement terminator.

Suppose that alpha and beta are int variables. The statement alpha = ++beta; is equivalent to the statement(s) ____.

The value of the expression 33/10, assuming both values are integral data types, is ____.

Suppose that alpha and beta are int variables. The statement alpha = --beta; is equivalent to the statement(s) ____.

A data type is called ____________________ if the variable or named constant of that type can store only one value at a time.
