Naming

There's some notes about "Naming" which I learned from "The Practice of Programming" by Brian W. Kernighan and Rob Pike. It's base on the book "The C Programming Language".

• use descriptive names for globals, short names for locals
• local variable
• i and j for loop indices
• p and q for pointers
• s and t for strings
• Programmers are often encourage to use long variable names regardless of context. This is a mistake: clarity is often achieved through brevity. (清楚與否需要透果簡潔以實現)
• initial capital letters for Globals, all capitals for CONSTANTS
• be consistent
• use active names for functions
• ex. getTime(), putChat()
• bool functions: isoctal()
• be accurate
