c-learning

Description

This repository is used to create a personal reference of more advanced C concepts; starting from the base axioms. The tutorials and examples assume basic knowledge of git. Please refer to a git tutorial via youtube or the official git documentation. The CLI used is git bash. While the instructions here in some cases may work with windows CLI or power-shell, it is expected that most will not without some amount of translation.

Disclaimer

The point of this repository is to document and create examples. The use of CMAKE is a "quick-and-dirty" setup because learning that tool extensively is not the main point of this repository. Furthermore the logging found in log.h and its respective source is just for fun rather than what I necessarily think a proper logging implementation. As it turns out, it is a decent example of using function pointers and macros in tandem.

Prerequisites

MINGW Compiler Installation for Windows 10

See the instructions in the resources folder.

C-Make

Go to: https://cmake.org/download/ and install it. This one is easier than mingw so no hand-holding here. Only thing to note is that you should ensure to enable adding it to path when prompted.

Generic Running Instructions

Quick Commands

Clean Build Directory

Use me to clean. Assumes ${cwd} is build.

cd .. && rm -r ./build && mkdir build && cd ./build

TODO: Add proper clean method.

Build Then Run

THEN:

cmake .. -G "MinGW Makefiles" -DRUN=<Integer Here> && mingw32-make && ./RUN.exe

Steps

1. If D.N.E.: mkdir build
2. cd ./build
3. cmake .. -G "MinGW Makefiles" -DRUN=<Specified RUN=integer>
4. mingw32-make
5. Run the resultant executable.

Topics

Recursion -- RUN=1

See file recursion_with_switch_statements.h and its source. To compile and run use: > mkdir ./build && cd ./build && cmake .. -G "MinGW Makefiles" -DRUN=1 && mingw32-make && ./RUN.exe

Pointers -- RUN=

W.I.P. - See file pointer_usage.h and it's source.

Function Pointers -- RUN=3

Initially it was just meant to enable formal logging, but log.h and its related source file seems to show a "flashy" way of using function pointers. I still wouldn't recommend doing what I've done with the logging in a professional environment.

To compile and run use: > mkdir ./build && cd ./build && cmake .. -G "MinGW Makefiles" -DRUN=3 && mingw32-make && ./RUN.exe
