Template for the C++ exercise

C++ exercise

This is a template for the C++ exercise. You can either fork it to your GitHub and then clone it, or clone it directly from here.

Getting the code

The tests are written using GTest environment, which is attached as a submodule to this repo. With Git 1.6.5 and later, you can clone the exercise and Google Test in one step:

git clone --recursive https://github.com/mzdun/cxx-exercise.git

Prior to that, to get the submodules, you must call submodule update by hand:

git clone https://github.com/mzdun/cxx-exercise.git
cd cxx-exercise
git submodule update --init --recursive

Building and running tests

CMake supports out-of-directory builds, which I strongly recommend. They keep the objects file away from the source code and cleaning the project and removing the build directory are almost the same operations.

mkdir build
cd build
cmake ..

CMake will use the best guess as to which compiler to use. On Windows it will consult registry and target newest Visual Studio/MSBuild combo. On Linux, it will use the cc and c++ programs. In case you are not happy with the results of c++ --version, you can force the compiler with CC and CXX environment variables. E.g. on Linux, where the shells support ad-hoc environment setting, you can force GCC 9 replacing the last line of the code above with:

CC=gcc-9 CXX=g++-9 cmake ..

Once the CMake finishes the configuration, it should leave you with set of build files. On Windows it will create a Visual Studio solution, cxx-exercise.sln and a .vcxproj for each target. On Linux it will create quite a number of Makefile files, so you can build and run the tests with:

make && ./tests/tests
