Write a c program for basic text manipulation ? What are you ? Retired? Unemployed ? Talk about a sledge hammer to crack a nut and reinventing the wheel !
There is no reason to even contemplate writing a c program to manipulate text unless you are doing something really really specialist and niche ... There are hundreds of perfectly good tools out there , and if you are a Linux or Mac user, all the best ones are built in (no doubt even windows powershell has some built in functions).
Also... between 1) PDF -> TXT and 2) Write your C Program.... you appear to have left out 1b) Data Validation....
GIGO as they say.... I've seen what these PDF to TXT conversion engines can do ....suffice to say I wouldn't want to be the one relying on the output of your "step 2)" if you're not going to be implementing any validation or QA !
