C Programming

Understand the machine underneath every language.

Build a precise mental model of compilation, pointers, arrays, structs and memory. C is small, unforgiving and the best way to understand what higher-level languages hide.

01Variables and operatorsDeclare typed variables, print them with format specifiers, and see how integer arithmetic and overflow behave. Challenge 10 min 02Control flow and loopsChoose between paths with if/else and switch, and repeat work with for and while loops. Challenge 12 min 03Functions and scopeDeclare functions with prototypes, pass values in, return values out, and respect where variables are visible. Challenge 12 min 04Strings and the standard libraryWork with null-terminated character arrays and the safe string functions from the standard library. Challenge 13 min 05Makefiles and debuggingAutomate a build with a minimal Makefile and catch bugs with warnings, gdb and sanitizers. Challenge 14 min 06Compilation and typesC is compiled ahead of time and has a small set of primitive types. Challenge 12 min 07Pointers and arraysA pointer stores an address; an array is a contiguous block of values. Challenge 15 min 08Structs and function designStructs group related data; functions should state who owns what. Challenge 14 min 09Dynamic memorymalloc reserves memory; free returns it. Every path must agree. Challenge 15 min 10Files, tools and debuggingReal C programs read input, report errors and are tested under pressure. Challenge 14 min
