PS I synthesize here in my own words what King teaches, re-write all his example programs, character by character, solve all the C exercises he hands out, and if I do not understand something fully I use Bermudez' CP: AMA Study Guide to find clarification. I comment to what King teaches cursively. I do not copy-paste anything from the book!

2.8 Layout of a C Program

King describes a C program as a series of 'tokens': groups of characters that together form a meaning and lose it if split. Identifiers, keywords, operators, +, -, punctuation marks, and string literals are all tokens.

printf ("Height: %d\n", height); 

consists of 7 tokens:
(1) printf                 > identifier
(2) (                        > punctuation
(3) "Height: %d\n"  > string literal
(4) ,                        > punctuation
(5) height               > identifier
(6) )                        > punctuation
(7) ;                        > punctuation

In most cases space between tokens is irrelevant. In most cases tokens can be crammed together, unless putting 2 tokens together causes them to merge into a third token. For example in the celsius.c program we could remove most of the empty space, provided we leave space between tokens as float and Fahrenheit.
