C++里的小括号是什么,该怎么处理
C++里的小括号是什么
我不明白，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？我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.

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。
