Learn C with Real Code Examples

Install a C compiler (GCC, Clang, or MSVC)

Set up an IDE or text editor (VS Code, Code::Blocks, CLion)

Write source code in `.c` files

Compile using `gcc filename.c -o output`

Run the compiled program via command line or IDE

Install GCC/Clang or MSVC

Set PATH to compiler binaries

Choose IDE or text editor

Write .c source files

Compile and test programs

Makefile - build instructions

.c files - source code

.h files - header declarations

bin/ - compiled binaries

lib/ - external libraries

gcc file.c -o output - compile C program

./output - run program

make - build using Makefile

gdb ./output - debug program

valgrind ./output - check memory errors

Supports ASCII, UTF-8, and other encodings

Wide character support via wchar.h

Strings can be localized externally

Libraries exist for multi-language support

Program logic remains independent of locale

Code accessible via compiler and editor

Cross-platform source code possible

Standardized libraries for portability

Supports internationalization via char encoding

Can interface with external APIs for accessibility

Primarily console/CLI applications

Optional libraries for GUI (GTK, Qt with C bindings)

Text-based UIs possible via ncurses

Graphics handled via external libraries

Focus on system and logic rather than styling

Variables store temporary state

Pointers reference memory directly

Heap and stack manage dynamic and automatic memory

Global variables maintain shared state

Functions encapsulate state for modularity

Arrays and structs organize data

Pointers manage dynamic memory

File I/O persists data externally

Memory leaks monitored via tools

Efficient memory layout for performance
