## Include Guards
If you are writing more than one class, you may run into strange compiler errors when you compile everything. This may be due to a problem with including your class files, which can be solved as follows: for a header file called myclass.h add these two lines at the very top of the header file:
```cpp
#ifndef __MYCLASS_H
#define __MYCLASS_H
```
and at the very bottom of your .h file, add this line:
```cpp
#endif
```
