(Yes, 'const' in C is a waste of time, and half the people using it 
don't appear to know what it means. Some people also like to use it 
practically everywhere so that you can no longer make out the actual 
code. The version in C++ is a more complicated form even further away 
from what people really want.

Neither have the simplicity of concept of Pascal's 'const', which is 
just a named value. Not a variable that won't change once initialised, 
not a parameter that won't be changed nor any addressable location.)
