Class Interface 1

[Akusei]

how do I use __interface? In C# if I declare an "interface" like so:

interface IPeople
{
   void Test();
}

Then declare a class that uses the interface

class Person : IPeople
{
   Person();
   
   void Test();
}

This makes the compiler happy because I have a class Person that is using the interface IPeople and Person has declared the "Test" function. If I comment out "void Test();" then the compiler has a fit, telling me to declare the Test function.

How can I get the same functionality in C++? I've tried the following with no luck, it compiles without errors or warning, when it should give me at least one error.

__interface IPeople
{
   void Test();
};

class Person : public IPeople
{
   Person();
   ~Person();

   //void Test();
};

This should throw an error as far as I understand it, but it compiles with no problems. How do I fix this?

BTW, I've also tried this

class IPeople
{
   virtual void Test() = 0;
};

class Person : public IPeople
{
   Person();
   ~Person();

   //virtual void Test();
};

Still no errors.

You will get a compile error if you try to instantiate the Person.

Ok, now I'm getting somewhere. Thanks for the info, however, now when I try to instantiate the class Person, it tells me that it cannot instantiate an abstract class. The compiler gives this error everytime I try to compile, even when I declare the Test function.

Then you're not declaring it properly. Show the code.

Your absolutely right; That was my dumb fault! I didn't look at the code close enough.

In the Interface I declared "void test();", in the class I declared "void Test();". Sorry about that.
