Short code examples to cover different C++ language features for studying purposes. Examples are commented so someone can follow them and also origin of the example if exists is also given. This is helpful when some seeks original source of the information.
You will need a C++ compiler with C++17 support, CMake version 3.8 or greater for generating a build files and Boost C++ library. One example shows how to use Google Test testing library to implement unit tests, thus that is also needed.
To install CMake you can either compile it yourself or install from APT repository. To compiler it yourself follow this guide. To install from APT run following
sudo apt install cmake
If installing from APT repository make sure it's version is at least 3.8 or
greater. To check that run cmake --version.
Google Test is included as a Git submodule and you need to initialize it after cloning because it is not automatically done for you. Do this with following on root of the project
git submodule init
git submodule update
To install Boost library you can download it from here or on Ubuntu run
sudo apt-get install libboost-all-dev
First make a build directory to root of the project, then cd into it
mkdir build
cd build
Then use CMake to the generate your system's preferred build files
cmake ..
Then compile examples with
cmake --build .
After successful compile executables will be available under build folder in the
same folder structure as examples in src folder. For instance running ellipsis
example with following from a build directory
./src/ellipsis/ellipsis
Study example's printing and source code what is happening. Source code is usually commented extensively to inform what is happening and what is being tested.
