Yes, or even better the whole memory. HeapAlloc does not initialize it.

No, you can add it into the loop below. To make a bit more clear what I mean:
You initialize "index" based on the nFont value, but here you access based on
the array index. Its not immediately obvious that the array index and nFont
value is the same.
