Is there anything wrong with this?
My program works perfectly with this code, as far as I can tell. I'm asking because all the examples I've seen only have constants on the right hand side. For example:PHP Code:int get_valid_grade_counter();
const int GRADE_COUNTER = get_valid_grade_counter();
float grade[GRADE_COUNTER];
PHP Code:#define MAX_NUMBER_OF_GRADES 16
float grade[MAX_NUMBER_OF_GRADES];
Well the former still counts as a variable length array, which is only fully supported in C99.
All the const is doing is making sure you get a diagnostic if you try to modify GRADE_COUNTER after the initialisation (say GRADE_COUNTER++).
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
This works with all C Compilers.Code:#define MAX_NUMBER_OF_GRADES 16 float grade[MAX_NUMBER_OF_GRADES];
The other one does NOT work with all C Compilers.
As already stated in this thread it works if you have variable length arrays.
