Exercise 1-5. Modify the temperature conversion program to print the table in reverse order, that is, from 300 degrees to 0. Approach The original K&R temperature program counts up: it starts fahr at 0, adds the step each iteration, and stops when fahr > 300. Reversing the table means changing exactly three things: (1) start …
Exercise 1-3. Modify the temperature conversion program to print a heading above the table. What the Base Program Does K&R Section 1.2 introduces a program that prints a Fahrenheit-to-Celsius conversion table from 0 to 300 in steps of 20. It uses integer arithmetic — celsius = 5 * (fahr – 32) / 9 — and …
Exercise 1-4. Write a program to print the corresponding Celsius to Fahrenheit table. Approach K&R Chapter 1 opens with a Fahrenheit-to-Celsius table, converting F values to Celsius using C = 5 × (F − 32) / 9. This exercise asks for the inverse: step through Celsius values (0, 20, 40, …, 300) and compute the …
Exercise 1-2. Experiment to find out what happens when printf‘s argument string contains \c, where c is some character not listed above. The escape sequences K&R lists in section 1.5 are: \n (newline), \t (tab), \b (backspace), \” (double quote), and \\ (backslash). The exercise asks what happens with everything else. Approach The key insight …
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 page covers the error-experimentation part of Exercise 1-1. The baseline working program is in Exercise 1-1a. Here we deliberately break it five different ways — and more importantly, learn …
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 page covers the printf side of Exercise 1-1: what the format string actually does, how escape sequences work, and what happens when you modify or multiply printf calls. For …
