Hey, I believe you would have already visited my profile by now. I'm having 3+ years of experience in C and C++ programming and I can easily make you understand all the C codes and clarify all the queries that you have, in a very simple and practical manner.
Besides, I'll also teach you how to search about your queries online, what keywords to use specifically and on what platforms to ask the questions, so that you don't have to pay anyone else again in the future to clarify your doubts.
I'm also offering you this service at the minimum permissible rate and always care about my clients. I assure you, even if you have any doubts in future, post our sessions together, you'll manage to search it by yourself using my taught methods or contact no one else except me.
I'm friendly and patient and will be able to clarify all your doubts in detail.
Give it a chance. You won't be disappointed :)
