Essential C

This note explains all the common features and techniques for the C language. The coverage is pretty quick, so it is most appropriate for someone with some programming background who needs to see how C works. Topics include variables, int types, floating point types, promotion, truncation, operators, control structures (if, while, for), functions, value parameters, reference parameters, structs, pointers, arrays, the pre-processor, and the standard C library functions.
