See chapter 5 of the book 'Mastering OpenCV with Practical Computer Vision Projects' and the code on GitHub here.

If you want to try other classifiers, the sample 'letter_recognition.cpp' is training different classifiers in the purpose of letter recognition. You have also many answers on that forum to very close questions that you could look at.
