intro_to_c_plus_plus

This should serve as a reference to use in a self guided walkthrough of the c++ tutorial at https://cplusplus.com/doc/tutorial/introduction/

Installation Requirements

1. Docker - https://www.docker.com/get-started/
2. gcc official docker image - docker pull gcc
3. Code editor(vscode, sublime, emacs, vim)
4. Git.

Take a second to read up on code editors and what docker is if you don't already know.

They're pretty cool.

Building images

Anytime you finish reading the section and its associated code, you should try to build and run the application. This will help you build confidence running the programs.

Bugs

If for some reason it doesn't build for you, try to debug, do some googling and submit a pull request to fix the bug.

This will help you get in the habit of reading, writing, and fixing code.

That said, I am not perfect and I do not expect nor do I guarantee that all of this code will run successfully on the first try at anytime. Debug your errors, I'll help if I can.

References

• GCC official docker docs - https://hub.docker.com/_/gcc/

This will build (compile) and run one of the console apps

$ cd <section_name_path> $ docker build -t <section_name>-image . $ docker run -it --rm --name my-running-app my-cool-app-image

Compile the app inside the Docker container, but do not run it

There may be occasions where it is not appropriate to run your app inside a container. To compile, but not run your app inside the Docker instance, you can write something like:

$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp gcc:4.9 gcc -o myapp myapp.c

This will add your current directory as a volume to the container, set the working directory to the volume, and run the command gcc -o myapp myapp.c - which tells gcc to compile the code in myapp.c and output the executable to myapp.
