0. Terminologies

 The word token refers to a part of a program that plays much the same role as a word in a sentenc: in some sense it means the same thing every time it appears.

 The part of a compiler that breaks a program up into tokens is often called a lexical analyzer.

2. Summery

- 1. = is not ==

 The title says it all.

- 2. & and | are not && or ||

 The title says it all.

- 3. Greedy lexical analysis

 The way to convert a C program to tokens is to move from left to right, taking the longest possible token each time. This strategy is also sometimes referred to as greedy, or, more colloquially, as the maximal munch strategy.

- 4. Integer constants

 Many C compilers accept 8 and 9 as "octal" digits without complaint. The meaning of this strange construct follows from the definition of octal numbers. For instance, 0195 means $1 \times 8^2+ 9 \times 8^1 + 5 \times 8^0$, which is equivalent to 141 (decimal) or 0215 (octal).

Important: ANSI C prohibits it.

- 5. Strings and characters

 Because an integer is usually large enough to hold several characters, some C compilers permit multiple characters in a character constant as well as a string constant. This means that writing 'yes' instead of "yes" may well go undetected.
