C++ Language/Expressions
Reference material by Wikibooks contributors. This retains its source identity and is not 411 news reporting.
Much of a C++ program consists of a sequence of "expressions".
An expression is some kind of "operator", along with the "operands" that it processes as its input.
When the program is running, the computer "evaluates" the expression (often producing a "value" as the result of that evaluation).
