Strings (cont.)
• Don't call strlen() on #defined strings or strings that are
in-lined
– Use (int)(sizeof(string)-1) or an appropriately defined macro
• See if a built in string function exists to meet your
use case
– There are many built in string functions, some obscure
• Iterate once through the string for complex operations
– Each pass through a string can be viewed as a linear search in cost
– For highly complex string operations consider implementing a
state machine
