Hi Reethika,
You should first begin with a language. C is taught in almost every college in first year. It is very easy to begin with, and you should learn C. Mycodeschool, thenewboston are excellent youtube channels to begin with. Practicing is very important for actually getting better at coding. Hackerrank is an excellent platform for practice problems. As for books, 'Let us C' by Yashavant Kanetkar is a book which has everything written in a simple and easy to understand language, you can either buy it or look for pdf online. You should use the book as a side-reference.
Feel free to message for any additional support.
Thanks
