What does the name after the closing class bracket means?

Question

I\'ve encountered this code example and I remembered I\'ve seen it before and I didn\'t know what it is for and what it does? I\'ve searched on the internet but without luck.

Answer 1

You declare variables using the format type variable_name;. For example:

A x;

Where A may be the name of a class.

But instead of using a pre-existing class type, you can also define the class at the same time as you declare a variable of the new class's type:

class { ... } x;

or define the class and give it a name:

class A { ... } x;

In C++ it is common to just define the class and give it a name, but leave off the variable:

class A { ... };

but you don't have to leave off the variable.
