C Program Examples

Most C tutorial sites are full of void main(), gets(), and outputs nobody ever ran. Every program I ship is compiled with gcc -Wall -Wextra at zero warnings and actually executed — the output you read is the output I got. Inside: 400+ C programs, all 91 K&R exercises solved, 9 topic quizzes (150+ questions) synced with a free Android app, real gdb/Valgrind/Make/CMake guides, and interview prep with tested code. Free, no signup, 100/100 PageSpeed. Solo project since 2011, rebuilt in 2026.
