Abbreviated Precedence Chart for C++ Operators

Module by: Kenneth Leroy Busbee. E-mail the author

Summary: An abbreviated precedence chart for C++ operators typically used in a modular structured programming fundamentals course.

Note: You are viewing an old version of this document. The latest version is available here.

An operator is a language-specific syntactical token (one or more symbols) that causes an action to be taken on one or more operands. The following item provides an abbreviated list of those C++ operators that are typically taught in a programming fundamentals course that teaches modular structured programming concepts.

Operators between a set of lines have the same precedence and associativity.

OPERATOR NAME             SYMBOL(S)   COMMENTS        ASSOCIATIVITY

===================================================================

function call             ()                          Left to Right

array index               []

-------------------------------------------------------------------

postfix increment         ++          unary           Right to Left

postfix decrement         --          unary

-------------------------------------------------------------------

dereference               *           unary           Right to Left

address                   &           unary

unary positive            +           unary

unary minus               -           unary

prefix increment          ++          unary

prefix decrement          --          unary

cast                      (type)      unary

sizeof                    sizeof      unary (compile time)

logical NOT               !           unary

-------------------------------------------------------------------

multiply                  *                           Left to Right

divide                    /

modulus                   %           remainder

-------------------------------------------------------------------

add                       +                           Left to Right

subtract                  -

-------------------------------------------------------------------

-------------------------------------------------------------------

logical OR                ||                          Left to Right

-------------------------------------------------------------------

assignment                =                           Right to Left

addition/assignment       +=

subtraction/assignment    -=

multiplication/assignment *=

division/assignment       /=

Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
