本人不清楚，改变优先级的小括号，就像(*p)[10]这种的，里面的小括号是什么啊？本人看它既不是运算符也不是C++标点符号，那它属于哪一部分呢？

//C++ Operators // Operators specify an evaluation to be performed on one of the following: // One operand (unary operator) // Two operands (binary operator) // Three operands (ternary operator) // The C++ language includes all C operators and adds several new operators. // Table 1.1 lists the operators available in Microsoft C++. // Operators follow a strict precedence which defines the evaluation order of //expressions containing these operators. Operators associate with either the //expression on their left or the expression on their right; this is called //“associativity.” Operators in the same group have equal precedence and are //evaluated left to right in an expression unless explicitly forced by a pair of //parentheses, ( ). // Table 1.1 shows the precedence and associativity of C++ operators // (from highest to lowest precedence). // //Table 1.1 C++ Operator Precedence and Associativity // The highest precedence level is at the top of the table. //+--+--+--+ //| Operator | Name or Meaning | Associativity | //+--+--+--+ //| :: | Scope resolution | None | //| :: | Global | None | //| [ ] | Array subscript | Left to right | //| ( ) | Function call | Left to right | //| ( ) | Conversion | None | //| . | Member selection (object) | Left to right | //| -> | Member selection (pointer) | Left to right | //| ++ | Postfix increment | None | //| -- | Postfix decrement | None | //| new | Allocate object | None | //| delete | Deallocate object | None | //| delete[ ] | Deallocate object | None | //| ++ | Prefix increment | None | //| -- | Prefix decrement | None | //| * | Dereference | None | //| & | Address-of | None | //| + | Unary plus | None | //| - | Arithmetic negation (unary) | None | //| ! | Logical NOT | None | //| ~ | Bitwise complement | None | //| sizeof | Size of object | None | //| sizeof ( ) | Size of type | None | //| typeid( ) | type name | None | //| (type) | Type cast (conversion) | Right to left | //| const_cast | Type cast (conversion) | None | //| dynamic_cast | Type cast (conversion) | None | //| reinterpret_cast | Type cast (conversion) | None | //| static_cast | Type cast (conversion) | None | //| .* | Apply pointer to class member (objects) | Left to right | //| ->* | Dereference pointer to class member | Left to right | //| * | Multiplication | Left to right | //| / | Division | Left to right | //| % | Remainder (modulus) | Left to right | //| + | Addition | Left to right | //| - | Subtraction | Left to right | //| << | Left shift | Left to right | //| >> | Right shift | Left to right | //| < | Less than | Left to right | //| > | Greater than | Left to right | //| <= | Less than or equal to | Left to right | //| >= | Greater than or equal to | Left to right | //| == | Equality | Left to right | //| != | Inequality | Left to right | //| & | Bitwise AND | Left to right | //| ^ | Bitwise exclusive OR | Left to right | //| | | Bitwise OR | Left to right | //| && | Logical AND | Left to right | //| || | Logical OR | Left to right | //| e1?e2:e3 | Conditional | Right to left | //| = | Assignment | Right to left | //| *= | Multiplication assignment | Right to left | //| /= | Division assignment | Right to left | //| %= | Modulus assignment | Right to left | //| += | Addition assignment | Right to left | //| -= | Subtraction assignment | Right to left | //| <<= | Left-shift assignment | Right to left | //| >>= | Right-shift assignment | Right to left | //| &= | Bitwise AND assignment | Right to left | //| |= | Bitwise inclusive OR assignment | Right to left | //| ^= | Bitwise exclusive OR assignment | Right to left | //| , | Comma | Left to right | //+--+--+--+

你可能只是想要对各种符号进行分类。
小括号“()”，可以看作是操作符的一种。用户确定代码执行的优先级。
而且加减乘除都是操作符，都可以通过代码重新定义操作符的行为。
你可以看看《C++ Primer 3rd Edition 中文完美版.pdf》的第四章和第十五章就知道了

算运算符的~
