Chapter 1: A Tutorial Introduction is where K&R C begins — and it moves faster than most C books. By exercise 1-8 you are counting characters by category; by 1-13 you are drawing histograms; by 1-22 you are folding long lines. The chapter uses only a tiny subset of C deliberately: loops, if/else, basic functions, …
Exercise 3-3. Write a function expand(s1,s2) that expands shorthand notations like a-z in the string s1 into the equivalent complete list abc…xyz in s2. Allow for letters or digits on either end of a range, and take care of cases like a-b-c and a-z0-9 and -a. Arrange that a leading or trailing – is taken …
Exercise 1-1. Run the “hello, world” program on your system. Experiment with leaving out parts of the program to see what error messages you get. This is the very first program in The C Programming Language by Kernighan and Ritchie — and for many people, the first C program they ever type. The exercise has …
