没有运算符^ +但是有一个一元运算符+（就像那里有一个
一元运算符 - ）你在这里使用。

There is no operator ^+ but there is an unary operator + (like there an
unary operator -) which you are using here.

没有^ +运算符。声明被解析为
c = a ^（+ b）;
There is no ^+ operator. The statement is being parsed as
c = a ^ (+b);

But the output is 30, it is acting same as the addition operator.
