• The C programming language was pioneered by Dennis Ritchie at AT&T Bell Laboratories.
• The most recent standard was adopted in 1999 called ANSI C99 or ISO/IEC 9899:1999.
• Programs should be written readablely so that they can be easily read eithe by the author or by somebody else.

• The meaning of ‘constant’:常數(shù) (我猜了很久才猜出來)
