I would recommend C: A Reference Manual (by Samuel P. Harbison and Guy L. Steele Jr.) along with K&R The C programming language. C has lots of edges where it's easy for a beginner to make mistakes. Say for example the minimal range of a char is -127 to 127 (yes, C cares 1's complement machines) or 0 to 255. Not knowing this may result in a code working in one machine while broken on others. So learning the standard is a must, especially, the undefined behaviors.
