About

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

Tasks list

1. I/O stream manipulators.
2. Proxy object.
3. Iterator.
4. Using of std::variant.
5. CSV parser by boost::spirit::x3.
6. JSON parser by boost::spirit::x3.
7. Type map to describe mapping of compile-time types to runtime values.
8. 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.

1. Install docker.

2. 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.

3. Within docker-session call the same command sequence like was done above (mkdir, cd, cmake, etc.).

4. 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

1. How to declare and define function within another function?

2. How to copy lambda?

3. 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;
   }
   

4. How to initialize members of the same class in different constructors?

5. 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.
