newbie help : lexer in c

[vaib]

hi to all . this may seem quite out of place . i've opted for building
a lexical analyzer using c for my summer project . i know the required
automata theory and i know c too . i've also read the 'lex and yacc'
and now i'm stuck and i'm still not able to figure out how to go about
starting the coding part or where to begin it .i would highly
appreciate if any of you expert out there could write me a simple plan
or algorithm that i should follow for this project . also if you any
good book or internet resource that can help me in designing a lexer ,
it would be very helpful . thanking all in anticipation.

Try this if you need more theory:

If you want to see some code in action, try the
Compilers and Compiler Generators, an Introduction with C++

Hope you'll find it helpful.
