I usually use a generic framework to code my plug-ins. In them, I use, for example, the line:

PluginDialog::SetContainer(_bc) { bc = _bc->GetClone(); }

Why does the bc has an underscore behind it? What does the underscore stands for? I mean, what is the difference between bc and _bc ?
Thank you in advance for any reply.

Hello Rui,

AFAIK, names that begins with an underscore are reserved for libraries like stl or for compilers it self.

So actually it is better to use bc_ instate of _bc.

But in some cases underscore are used to do something like this.

  
class SomeClass  
{  
    SomeClass(BaseContainer &_bc) : bc(_bc) {}  
    BaseContainer bc;  
};  
  
// I would prefer to use something like this  
class SomeClass  
{  
    SomeClass(BaseContainer &bc;) : m_bc(bc) {}  
    BaseContainer m_bc;  
};  

If this is not answer to you question then I have understand you question wrong.

So, the underscore is just another character to make the variable _bc different from bc?
The underscore has no special function like, for example the ! or & characters?
That means that I could very well write:

PluginDialog::SetContainer(other_bc) { bc = other_bc->GetClone(); }

instead of:

PluginDialog::SetContainer(_bc) { bc = _bc->GetClone(); }

is it?
