Quick Start to C Programming - Coming from another language

Explain booleans and if statements in C, where true and false map to 1 and 0, the std bool header, and common practices like parentheses, == true, and yoda conditions.

Learn how to use for, while, and do while loops in C and C++, including when to choose each loop and why do while guarantees at least one iteration.

Learn how to declare and define functions in a single source file, why the main function is the entry point, and how declarations enable calls across files with header files.

Explore debugging C and C++ with gdb, lldb, or MSVC, compile in debug mode, set breakpoints, and use the VS code extension for easier debugging, noting release mode optimizations.

Learn how the coding exercises are organized in each chapter, with an underscore exercise folder containing the exercise.md description, starting code to implement, and test cases to verify your solution.

Learn how call by value copies arguments into parameters, and call by reference uses pointers to modify the caller's variables, enabling multiple outputs in C.

Learn how C and C++ arrays store a single data type with a fixed compile-time size, use zero-based indexing, and support initialization.

Learn how arrays decay to pointers when passed to functions and why you must pass the array length as a parameter, with const input and mean calculation in C.

Learn to store text in C with character arrays and strings, including null terminators and printing with %s. Discover how to initialize, update by indexing, and avoid out-of-bounds access.

Learn to use clang-format, the common C and C++ formatter in VS Code, configured via dot clang-format and optional settings on save to produce a consistent, unified code layout.

Clang-tidy shows how a static code linter analyzes C/C++ code, flags issues like magic numbers and narrowing conversions, and can be configured in VS Code to run on save.

Learn to allocate memory for a dynamically sized array with malloc on the heap, cast the void pointer to the right type, check for null, and free it.

Explore null and void pointers in C, learn how to initialize, check for null, and dereference safely while managing heap memory with malloc and free to avoid invalid addresses.

Learn how struct padding affects memory usage and how aligning by the largest type, then ordering fields from largest to smallest, reduces padding with examples using int, float, and double.

Open and close files with fopen and fclose, read with fscanf, transform values, and write results with fprintf to an output file, using absolute paths.

Learn how to read and write lines with fgets and fputs, using a while loop, fixed line length, and basic string to number conversions via atoi.

Store and read a binary file containing a four-byte integer and a four-byte float using f write and f read, with the structure's address and size.

Explore obtaining the current time in C with the time function and Unix timestamp, then format it using localtime and struct tm for readable day, date, and time.

Explore macros and preprocessor defines in C and C++, including ndebug vs debug, ifdef/ifndef, and conditional compilation to enable logging, asserts, and test code for debug versus release builds.

Explore how the C standard library's qsort sorts an array via a user defined comparator, with const void pointers, size, and a function pointer, including casting to a double pointer.

Conclude with a quick start to the C programming language, highlighting its role as a foundation for many other languages and encouraging a review and topic suggestions for other courses.
