The precedence of C + + operator and its memory method __c++

Priority Level	operator	Description	Example	combination of
1	() [] -> . :: ++ --	Bracket operator for adjusting precedence Array Subscript access operator To access a member's operator by pointing to an object's pointer To access a member's operator through the object itself Scope operator Post self-increment operator Post Self subtraction operator	(A + B)/4; ARRAY[4] = 2; Ptr->age = 34; Obj.age = 34; Class::age = 2; for (i = 0; i < i++) ... for (i = i > 0; i--) ...	From left to right
2	! ~ ++ -- - + * & (type) sizeof	Logical fetch inverse operator Bitwise reverse (by bit to fill) Forward self-increment operator Forward self-subtraction operator Unary take negative operator Unary take positive operator Solution Reference operator Take address operator Type conversion operators Returns the number of bytes used by the object operator	if (!done) ... Flags = ~flags; for (i = 0; i < ++i) ... for (i = 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	->* .*	To access a member's operator on the pointer by a pointer to a member To access a member's operator on an object by pointing to a pointer to a member	Ptr->*var = 24; Obj.*var = 24;	From left to right
4	* / %	Multiplication operator Division operator Take the remainder operator	int i = 2 * 4; float F = 10/3; int rem = 4% 3;	From left to right
5	+ -	Addition operator Subtraction operator	int i = 2 + 3; int i = 5-1;	From left to right
6	<< >>	Bitwise left-shift operator Bitwise right-shift operator	int flags = << 1; int flags = >> 1;	From left to right
7	< <= > >=	Less than comparison operator Less than or equal to comparison operator Greater than comparison operator Greater than or equal to comparison operator	if (I < 42) ... if (i <= 42) ... if (i > 42) ... if (i >= 42) ...	From 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 (remainder) Compound assignment operators (bitwise AND) Compound assignment operator (bitwise XOR OR) Compound assignment operator (bitwise OR) Compound assignment operator (move left by bit) Compound assignment operator (move right by bit)	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
