you’ll need: 1)http client(with SSL) 2)regular expresion and/or json parser and/or html parser 3) understanding of 2) i.e. how to effectively use them (regex...) to grab target data. I once wrote an instagram downloader in C++. I used my own http client, regex (C++), and a json parser. To make http client you need to have the understanding of low level socket programming. For SSL support I used openssl. As earlier answerer mentioned, it’s good to use already available options then reinventing the wheel. But if you want to do from scratch, then you have to write every single libraries I mentioned above from scratch. Good luck. N.B. I forgot to mention if you use C then you need to have your own containers (vector, list...) and good understanding of dynamic memory management.

Yogeshwaran well, you said you want to write everything from scratch. if you want to write an http client how are you gonna store data? C fixed array? Everything is gonna be out of control soon if you follow this way. About web scraping: let’s say you want to scrap 100 http urls. where are you gonna store those? raw array won’t cut out for this when you won’t even know the length of data beforehand. I’d suggest something like C++ or Rust if you want to use any system language for web scraping. Or find good open source libraries for C.
