*Assuming that a project has been using the C class prefix for a long time, and it would be a waste of time to change at a late stage, and that the person who originally wrote the style guide has been hit by a bus, and that there are no structs in the code already...*

It's a pretty trivial question, but if a C++ code style guide says "use C for class name prefix" then should this be taken to mean also use C for struct prefix also, or should we use something different, like S for example.

```
class CFoo { };
struct CBar { };

```

... or ...

```
class CFoo { };
struct Bar { };

```
