This month’s Exercise is about finding the limits, or how large a signed or unsigned char value can get before it flips over to negative or to zero. And the trick is performing this feat in your code without using the defined constants for a char data type available in the limits.h header file.

As a wrap-up for my ctype questions, this month’s Exercise is to write a ctype function that converts lowercase Greek letters to uppercase and vice-versa. This challenge isn’t a steep hill to climb, once you know the pattern of Unicode Greek letter values, and ignore the required accent and breathing marks that frequently adorn various letters.

The challenge for this month’s Exercise is to use pointers to work through a multi-dimensional array. As I mentioned in the exercise post, multi-dimensional arrays are all stored as a single-dimension where the compiler calculates offsets for rows and columns (and more) for you.
