5. Do the exercise

After having modified the README, it is time to do the exercise.

Each chapter describes an exercise (in README.md) and has a file called main.cpp. main.cpp is where you must put your code.

To do an exercise, edit the main.cpp file. Usually main.cpp contains already some incomplete code to get you started, or dictate some structure. For example, the hello chapter has this code in main.cpp:

main() {}

You can use any editor or IDE to build and run your code.

Some examples:

• Using GCC/g++ from the command line
• Using Qt Creator

For some exercises, you will also need to:

• run your program with arguments.
• get 100% code coverage
• get a lower cyclomatic complexity

After having done the exercise, push your code to let git upload your proposed solution.
