C + + operator precedence

Priority level

	operator	description	examples	of associativity
1	() [] - . :: ++ --	The parentheses operator that adjusts the precedence Array Subscript access operator To access a member's operator by pointing to the object's pointer Operator that accesses members through the object itself Scope operator Post increment operator Post-decrement operator	(A + B)/4; ARRAY[4] = 2; Ptr->age = 34; Obj.age = 34; Class::age = 2; for (i = 0; i <; i++) ... for (i = ten; i > 0; i--) ...	From left to right
2	! ~ + + -- - + * & (type) sizeof	logical take inverse operator bitwise Inverse ( Bitwise complement) pre-increment operator pre-decrement operator unary take negative operator unary positive operator dereference operator fetch address operator type conversion operator Returns the number of bytes occupied by the object operator	if (!done) ... Flags = ~flags; for (i = 0; i <; ++i) ... for (i = ten; i > 0; i.) ... int i =-1; int i = +1; data = *ptr; Address = &obj; int i = (int) floatnum; int size = sizeof (floatnum);	From right to left
3	->*		ptr->*var =; Obj.*var =;	Left to right
4	* / %	multiplication operator Division operator fetch remainder operator	int i = 2 * 4; float f = 10/3; int rem = 4 3;	Left to right
5	+ -	addition operator subtraction operator	int i = 2 + 3; int i = 5-1;	Left to right
6	<< >>	bitwise left shift operator	int flags = << 1; int flags = >> 1;	Left to right
7	< <= >=	Less than the comparison operator less than or equal to comparison operator greater than comparison operator greater than or equal to comparison operator	if (i < ) ... if (i <=) ... if (i >) ... if (i >=) ...	Left to right
8	== !=	equals comparison operator Not equal to comparison operator	if (i = = 42) ... if (i! = 42) ...	From left to right
9	&	Bitwise AND operator	Flags = flags & 42;	From left to right
10	^	Bitwise XOR OR operator	Flags = flags ^ 42;	From left to right
11	|	Bitwise OR operator	Flags = Flags | 42;	From left to right
12	&&	Logic and operators	if (Conditiona && conditionb) ...	From left to right
13	||	Logical OR operator	if (Conditiona | | conditionb) ...	From left to right
14	? :	Ternary conditional operator	int i = (a > B)? A:B;	From right to left
15	= + = -= *= /= %= &= ^= |= <<= >>=	assignment operator Compound assignment operator ( addition) compound assignment operator (subtraction) compound assignment operator (multiplication) Compound assignment operator (division) compound assignment operator (take surplus) Compound assignment operator (bitwise VS) Compound assignment operator (bitwise XOR) Compound assignment operator (bitwise OR) Compound assignment operator (bitwise left shift) Compound assignment operator (bitwise right SHIFT)	int a = b; A + = 3; B-= 4; A *= 5; A/= 2; A%= 3; Flags &= new_flags; Flags ^= new_flags; Flags |= new_flags; Flags <<= 2; Flags >>= 2;	From right to left
16	,	Comma operator	for (i = 0, j = 0; i <; i++, J + +) ...	From left to right
