About

This project is intended to test students skills in C++ language.

Tasks list

I/O stream manipulators.
Proxy object.
Iterator.
Using of std::variant.
CSV parser by boost::spirit::x3.
JSON parser by boost::spirit::x3.
Type map to describe mapping of compile-time types to runtime values.
Tests for strided range.

How to build?

cmake

Just use cmake:

$ cmake -B build .
$ make -C build -j
$ make -C build test

If you want to work with particular project, just uncomment (remove # sign) string add_subdirectory with the project name. You can launch the tests from this project only (shown for <myproject>):

build/ $ make -j
build/ $ ctest -R <myproject> -V

The flag -V shows detailed report.

Or use catch executable directly:

build/ $ ./<myproject>/tests_<myproject>

docker

Another approach is to use docker image igsha/cxx-miet.

Install docker.
Pull image and start docker-session:
```
$ docker run -u `id -u`:`id -g` -v $PWD:/data -it igsha/cxx-miet:0.2
bash-4.4$ <-- this means you are in a docker-session
```
- once downloaded session will be available locally;
- flag -u `id -u`:`id -g` is used to bring the same permissions into docker as your local user permissions;
- flag -v $PWD:/data is used to mount your current source directory into docker like folder /data;
- notes for Windows users: you don't need flag -u, replace $PWD with the name of current directory.
Within docker-session call the same command sequence like was done above (mkdir, cd, cmake, etc.).
To exit docker-session press Ctrl-D or type exit command.

nix-shell

If you don't use NixOS, you can still use nix-shell on linux-like systems.

Install nix environment by running the command curl https://nixos.org/nix/install | sh and answer several questions. Point to the project root directory and run nix-shell. Then just follow cmake subsection instructions.

How to work with projects

Each project is a subproject with

CMakeLists.txt;
include that represent the "source" of a project;
tests is a main part to check task;
README.rst that has some useful information about the project.

Students should work only with files inside include folder. The main criteria is to pass all tests of a project.

How to answer in-source questions

There are some questions in the source of projects that have the form of C-comments //?. Print the answer just below a question using the form of C-comment //!.

Use these questions as a hint to a task.

Additional questions

How to declare and define function within another function?
How to copy lambda?

How to call non-constant method of a member within constant method?

struct cba
{
    std::ostream& o;
}

struct abc
{
    void mark() const
    {
        obj.o << 123;
    }

    ?cba? obj;
}

How to initialize members of the same class in different constructors?
How to initialize a member in separate function within member initializer list?

[optional] Write complete project (CMakeLists.txt, folder hierarchy and tests). Themes:

INI-parser with EBNF in comments;
implement iterator of multidimensional array with the ability to choose the direction of iterations (by x-, y- or z-axis, etc.);
provide example to work with google-protobuf.
