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?

回答1:

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.

回答2:

You cannot overload the conditional operator.

回答3:

No, you can't overload the conditional operator, since it's simply shorthand for a simple if..else block.

You can however overload the operators used in the condition, but not for primitive types such as int, like you have in your example above.
