如何重载条件运算符？ [英] How to overload the conditional operator?

问题描述

可能的重复：

操作员重载

我不知道如何在cpp中重载条件运算符？

  int a，b，c; 
 
 a = 10; 
 b = 11; 
 c =（a> b）？ a：b; 
  

是否有可能？

方案

几个操作符不能重载。这些运算符将名称而不是对象作为其右操作数：

• 直接成员访问




• 范围解析（::）





此外，新的typecast操作符：static_cast<>，dynamic_cast<>，reinterpret_cast< ，and const_cast<>，并且＃和##预处理器令牌不能重载。

I was wonder how can I over load the Conditional operator in cpp?

int a,b,c;

  a=10;
  b=11;
  c = (a>b) ? a : b;

Is it possible?

解决方案

Several operators cannot be overloaded. These operators take a name, rather than an object, as their right operand:

• Direct member access (.)

• Deference pointer to class member (.*)

• Scope resolution (::)

• Size of (sizeof)

The conditional operator (?:) also cannot be overloaded.

Additionally, the new typecast operators: static_cast<>, dynamic_cast<>, reinterpret_cast<>, and const_cast<>, and the # and ## preprocessor tokens cannot be overloaded.
