I'd like to recommend the books:
C All-In-One Desk Reference For Dummies by Dan Gookin (read first)
play with the language, write programs, experiment.
Now, once you get a bit better, go read The C Programming Language by Brian Kernighan and Dennis Ritchie .
The 2nd book is referred to as "K&R C" most of the time.
Also, check out the YouTube channels Handmade Hero,
