Double Constant???

[Analyzer]

Why do some parameter values have two "Constant" symbols on them... Example:

void Function( constant int number constant){
~~~~~~~~
~~~~~
~~~~
}

That cannot and will not compile. Even if you removed the ~ and changed constant to const, it is still wrong.

Yeah, I know I wrote it wrong. The Example Im confused about is this... And this is from a book.


Function( const char * const variable1, const char* const last)

why are there two const keywords for 1 parameter varaible?

[LB]

They are both constant pointers to constant characters.

[Analyzer]

i see.

The const before the * means that you can't modify the object pointed to (char). The const after the * means you can't modify the pointer (variable1) to make it point elsewhere.
