re: defining variables when set to a value?

#1

Recently I came across this peice of code…


   class Foo
   {
     public:
   	struct Bar
   	  {
   		short varA;
   		Bar():varA(0) {} // <- huh?
   	  };
   };

Does anyone know what is going on there? Looks like some sort of inheriting going on but I am not sure as to why.
Thanks in advance

Is the C++ way for variable initialization. It’s the same as if you do:

struct Bar
{
	short varA;

	Bar()
	{
		varA = 0;
	}
};

thanks for the reply halfvector, this kind of assigment is new to me. There is no need to use semicolons at the end and its very odd.
Any ideas what the term to such defination? Its hards searching for help on google for such assigments.

Thanks
