c++要背的表是什么表

C++ 运算符优先级

本列表中运算符优先级从上往下，优先级依次降低。优先级最高的为::(作用域解析运算符)。

Precedence	Operator	Description	Associativity
1	`::`	Scope resolution	Left-to-right
2	`++` `--`	Suffix/postfix increment and decrement
	`type()` `type{}`	Function-style type cast
	`()`	Function call
	`[]`	Array subscripting
	`.`	Element selection by reference
	`->`	Element selection through pointer
3	`++` `--`	Prefix increment and decrement	Right-to-left
	`+` `-`	Unary plus and minus
	`!` `~`	Logical NOT and bitwise NOT
	`(type)`	C-style type cast
	`*`	Indirection (dereference)
	`&`	Address-of
	`sizeof`	Size-of^{[note 1]}
	`new`, `new[]`	Dynamic memory allocation
	`delete`, `delete[]`	Dynamic memory deallocation
4	`.` `->`	Pointer to member	Left-to-right
5	`*` `/` `%`	Multiplication, division, and remainder
6	`+` `-`	Addition and subtraction
7	`<<` `>>`	Bitwise left shift and right shift
8	`<` `<=`	For relational operators < and ≤ respectively
8	`>` `>=`	For relational operators > and ≥ respectively
9	`==` `!=`	For relational = and ≠ respectively
10	`&`	Bitwise AND
11	`^`	Bitwise XOR (exclusive or)
12	`\|`	Bitwise OR (inclusive or)
13	`&&`	Logical AND
14	`\|\|`	Logical OR
15	`?:`	Ternary conditional^{[note 2]}	Right-to-left
	`=`	Direct assignment (provided by default for C++ classes)
	`+=` `-=`	Assignment by sum and difference
	`*=` `/=` `%=`	Assignment by product, quotient, and remainder
	`<<=` `>>=`	Assignment by bitwise left shift and right shift
	`&=` `^=` `\|=`	Assignment by bitwise AND, XOR, and OR
16	`throw`	Throw operator (for exceptions)
17	`,`	Comma	Left-to-right
