Part 2 of TechVani's free C Learning Guide is live: variables, data types and printf scanf in C.

This part covers how C stores and moves data: int, float, char and the other basic types, declaring and naming variables, reading input with scanf, printing with printf and its format specifiers, and the small conversion and sizing details exams love to test.

Every code sample in the guide is actually compiled and run, with the checked output shown beside it - no invented results.
