Exercise 7-9. Functions like isupper can be implemented to save space or to save time. Explore both possibilities. Standard library character-classification functions like isupper are typically implemented as macros. There are two design axes: Save time: use a precomputed lookup table — one array access, no branches, O(1) at maximum cache efficiency Save space: use …
Exercise 6-2. Write a program that reads a C program and prints in alphabetical order each group of variable names that are identical in the first 6 characters, but different somewhere thereafter. Don’t count words within strings and comments. Make 6 a parameter. The strategy: Use the improved getword from Exercise 6-1 to read identifiers, …
