单目正和单目负运算符是不是算术运算符里优先级最高的？
单目正运算符和单目负运算符两者的优先级谁高谁低？或者优先级一样？
这里有点不清楚
在 C 语言中，单目正和单目负运算符的优先级是一样的，都是算术运算符优先级里面最高的。这意味着在表达式中，单目正和单目负运算符会先被计算。
例如，在表达式 "-1 + 3" 中，单目负运算符会先于加法运算符被计算，因此最终结果是 "-1 + 3 = 2"。
望采纳！！！
单目正和单目负运算符确实是算术运算符中优先级最高的。单目正运算符和单目负运算符两者优先级相同。

//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.
