C for Beginners

Compile and run a first program, read the parts of a C file, store values in typed variables, and steer execution with decisions and loops.

Collect values in arrays, move code into reusable functions, reach memory through pointers, and group text and fields in strings and structs.

Walk arrays with pointer arithmetic, add levels of indirection, allocate and release heap memory, and choose storage classes that match how long a value must live.

Use string.h without its sharp edges, read lines safely with fgets, and build strings inside buffers whose capacity you track.

Model records with nested structs, enums and unions, sort arrays of them, then work with text files, command-line arguments and recursive linked structures.
