 | Many times [inlinecode]strtok[/inlinecode] is recommended for parsing a string; I don't care for [inlinecode]strtok[/inlinecode]. Why? [list][*]It modifies the incoming string, so it cannot be used with string literals or other constant strings. [*]The identity of the delimiting character is lost. [*]It uses a static buffer while parsing, so it's not … |
