C Operator Precedence Table

Source: http://www.difranco.net/compsci/C_Operator_Precedence_Table.htm

This page lists C operators in order of precedence (highest to lowest). Their associativity indicates in what order operators of equal precedence in an expression are applied. Operator Description Associativity ( ) [ ] . -> ++ — Parentheses (function call) (see Note 1) Brackets (array subscript) Member selection via object name Member selection via pointer Postfix increment/decrement (see Note 2) left-to-right ++ — + – ! ~ (type) * & sizeof Prefix increment/decrement Unary plus/minus Logical negation/bitwise complement Cast (convert value to temporary value of type) Dereference Address (of operand) Determine size in bytes on this implementation right-to-left *  /  % Multiplication/division/modulus left-to-right +  – Addition/subtraction left-to-right <<  >> Bitwise shift left, Bitwise shift right left-to-right <  <= >  >= Relational less than/less than or equal to Relational greater than/greater than or equal to left-to-right ==  != Relational is equal to/is not equal to left-to-right & Bitwise AND left-to-right ^ Bitwise exclusive OR left-to-right | Bitwise inclusive OR left-to-right && Logical AND left-to-right | | Logical OR left-to-right ? : Ternary conditional right-to-left = +=  -= *=  /= %= &= ^=  |= <<=  >>= Assignment Addition/subtraction assignment Multiplication/division assignment Modulus/bitwise AND assignment Bitwise exclusive/inclusive OR assignment Bitwise shift left/right assignment right-to-left , Comma (separate expressions) left-to-right Note 1: Parentheses are also used to group sub-expressions to force a different precedence; such parenthetical expressions can be nested and are evaluated from inner to outer. Note 2: Postfix increment/decrement have high precedence, but the actual increment or decrement of the operand is delayed (to be accomplished sometime before the statement completes execution). So in the statement y = x * z++; the current value of z is used to evaluate the expression (i.e., z++ evaluates to z) and z only incremented after all else is done. See postinc.c for another example.
