Glossary
--------

assignment:
    A statement that assigns a value to a variable.

composition:
    The ability to combine simple expressions and statements into
    compound statements and expressions in order to represent complex
    computations concisely.

declaration:
    A statement that creates a new variable and determines its type.

expression:
    A combination of variables, operators and values that represents a
    single result value. Expressions also have types, as determined by
    their operators and operands.

keyword:
    A reserved word that is used by the compiler to parse programs.
    Examples we have seen include int, void and endl.

modulus:
    An operator that works on integers and yields the remainder when one
    number is divided by another. In C++ it is denoted with a percent
    sign (%).

operator:
    A special symbol that represents a simple computation like addition
    or multiplication.

operand:
    One of the values on which an operator operates.

precedence:
    The order in which operations are evaluated.

statement:
    A line of code that represents a command or action. So far, the
    statements we have seen are declarations, assignments, and output
    statements.

type:
    A set of values. The types we have seen are integers (int in C++)
    and characters ( char in C++).

variable:
    A named storage location for values. All variables have a type,
    which determines which values it can store.

value:
    A letter, or number, or other thing that can be stored in a
    variable.
