Inner classes

[jcafaro10]

I have a .cc file with several methods in it. I also have some structs declared at the top of the file that I use inside of the .cc file. I'd like these structs to have methods, ie. I'd like the structs to be classes. Is that only a matter of replacing the word struct with class?

Currently I have:

struct A
{
     int a1;
     int a2;
}

I'd like to have:

class A
{
     int a1;
     int a2;
     int add(void)
     {
           return a1+a2;
     }
}

Is that all I have to do?

You can put methods inside a struct too.

I didn't know that. Thanks

In C++, a struct is a class with base classes (i.e., inheritance) and members public by default. As Stroustrup's C++ glossary entry on struct puts it, they are "most often used for data structures without member functions or class invariants, as in C-style programming".
