Summary
We should declare constants in headers and define them in source files.
But this commit is only aimed at compound types.
I don't know if it is necessary to do the same thing to fundamental types.
I used this command to find all of the constant definitions in header files.
`find . -name "*.h" | xargs grep -e "^const .*=.*"`
And here is what I found:
```

Any comments would be appreciated.
Thanks.
