I found this link http://wiki.ros.org/CppStyleGuide#Enu... talk about using enum. But I haven't been able to use it correctly. Could you please show me an example how to use it? Thank you very much.
Does this help?
namespace Choices
{
enum Choice
{
Choice1,
Choice2,
Choice3
};
}
typedef Choices::Choice Choice;
int foo() {
Choice c = Choices::Choice1;
switch(c) {
case Choices::Choice1:
// TODO: something
break;
case Choices::Choice2:
// TODO: something
break;
case Choices::Choice3:
// TODO: something
break;
default:
// TODO: something
break;
}
}
(tested and compiles with gcc 4.8.4)
Yes, it helps a lot. Thanks ahendrix.
But the correct should be Choices::Choice c = Choices::Choice1;
I am sorry, you are correct. I define the typedef wrong so in declaring the variable I got an error which it didn't happen when I have the namespace. This makes me confused. Thank you very much :D
