parsing contents of files

[bobo12]

hi ppl,
i am used to using StringTokenizer in Java to help me parse for certain phrases and look for certain substrings within contents of file. I was wondering if there are built in classes in c that will allow me to do the same thing.

suppose I want to count the # of times a particular client downloaded a certain file in web logs. this is just an expl to give u a flavor of what i would like to do.

See regcomp, strcmp, strstr, strtok.
There are also plenty of homegrown ways and no end
of 'make it simple' libraries and apis. Just do a
google search. This seems a decent start:

You could also go for the full blown lex-yacc parsing thing. The freeware versions are flex (lex) and bison (yacc). They are basically BNF for LALR syntax converted into state machines.

1. The C Language has no any classes.
2. As usually programmers use strstr(), strchr(), strpbrk(), strcspn() etc RTL functions to search - and strtok to tokenize...
3. As usually no need in any other tools to solve ordinary (99.9%)problems...
