About

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

Tasks list

1. I/O stream manipulators.
2. Iterator.
3. Proxy object.
4. Using of std::variant.
5. Parsers by boost::spirit::x3:
   • csv;
   • json.
6. Type map to describe mapping of compile-time types to runtime values.

How to build?

Just use cmake:

$ mkdir build
$ cd build
build/ $ cmake ..
build/ $ make -j
build/ $ ctest

If you want to work with particular project:

build/ $ cmake ../iterator
build/ $ make -j
build/ $ ctest

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 $PWD:/data -it igsha/cxx-miet:0.1
   bash-4.4$ <-- this means you are in 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. Inside 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.

How to work with projects

Each project is a complete cmake-project with

• CMakeLists.txt;
• include that represent "source" of a project;
• tests - is a main part to check task.

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.
