Ask HN: Learning C++ for Java developers

2 points by dcwilson 12y ago ↗ HN

Hi,

I'm a Java developer who's developed an interest working with a couple C++ based projects (OpenCV and QGIS in particular). I know that there are bindings for other languages for both of these projects, but I feel its time to buckle down and learn C++.

Does the community have any recommendations for learning C++ from the perspective of someone who has only worked with Java and Python in their educational/professional career? I also want to make sure I'm learning modern best practices and not outdated techniques, which is a hazard of Googling for random web tutorials.

check out some good C++ open source projects, like Chrome from Google and Folly from Facebook.

I used this book [0] for my C++ course at uni a few semesters ago and found it rather easy to follow and Weiss does a good job going through the differences between Java and C++.

The biggest difference for me from Java is the fact you have to manage your own memory as there is no garbage collector to clean up after you in C++. This book covers memory management, operator overloading, and functors quite well.
