code in dot H files

[VictorN]

Question:
Is there a possible advantage in writing the code in the dot H file rather than the dot CPP file?

Seems to me its better to put all the code in one place.

No, it is definately not template code.

Then I don't see any advantage in putting the implementation code in the dot H file.
Instead, there is a disadvantage: if you change something in the implementation being in .h file then all the cpp files that #include this header will be recompiled.
