TCPL2 Exercise Solutions

This repository will contain solutions for all the exercises found on the book "The C Programming Language, 2nd ed" by Kernighan and Ritchie (or at least, I sure hope it will).

What to expect from the solutions?

Solutions will use only those features of C that have been covered in the book by the point at which the exercise appears.

Some remarks regarding C89

Since the book itself was written when the ANSI C standard was the C89 standard, all the code was written to comply with it. Specifically, all declarations of main return an int and take no arguments (where appropriate). Also, main always returns an int explicitly (usually 0):

int main(void) {
    ...
    return 0;
}

To ensure compliance with the C89 standard, all the code has been compiled with:

gcc -std=c89 -pedantic -Wall -Wextra ...
