C++ Operator Precedence and Associativity

This page lists all C++ operators in order of their precedence (highest to lowest).

Their associativity indicates in what order operators of equal precedence in an expression are applied.

Operator	Description	Associativity
::	Binary/unary scope resolution	l-to-r
( ) [ ] . -> ++ -- typeid dynamic_cast<type> static_cast<type> reinterpret_cast<type> const_cast<type>	Parentheses (grouping) Brackets (array subscript) Member selection via object name Member selection via pointer Unary postincrement Unary postdecrement Run-time type information Run-time type-checked cast Compile-time type-checked cast Cast for non-standard conversions Cast away const-ness	l-to-r
++  -- +  - !  ~ ( type ) sizeof & * new new [ ] delete delete [ ]	Unary preincrement/predecrement Unary plus/minus Unary logical negation/complement Unary cast (change type) Determine size in bytes Address Dereference Dynamic memory allocation Dynamic array allocation Dynamic memory deallocation Dynamic array deallocation	r-to-l
.* ->*	Pointer to member via object Pointer to member via pointer	l-to-r
*    /    %	Multiplication/division/modulus	l-to-r
+  -	Addition/subtraction	l-to-r
<<   >>	Bitwise shift left/right	l-to-r
<   <= >   >=	Relational less than/or equal to Relational greater than/or equal to	l-to-r
==   !=	Relational is/is not equal to	l-to-r
&	Bitwise AND	l-to-r
^	Bitwise exclusive OR	l-to-r
|	Bitwise inclusive OR	l-to-r
&&	Logical AND	l-to-r
||	Logical OR	l-to-r
?:	Ternary conditional	r-to-l
= +=   -= *=   /= %=   &= ^=   |= <<=  >>=	Assignment Addition/subtraction assignment Multiplication/division assignment Modulus/bitwise AND assignment Bitwise exclusive/inclusive OR Bitwise shift left/right assignment	r-to-l
,	Comma (separate expressions)	l-to-r
