Learning C++ is one of the best languages to learn accounting to many people I know. But to learn C++, it is a good Idea to find a mentor or friends who know it to teach you, join programming clubs and read computer forums and books. Especially books because that Is actually one of the best ways to learn. I have learned this and many of my friends would also agree. But perhaps the best way I know is programming language schools or free classes. These are the ways to jump start. If you have more questions, ask me in private chats. I have some contacts/sites that you can learn from.
