copied!<p>OK, for that particular example:</p> <ul> <li>you can get the time services from the standard library <a href="http://www.cplusplus.com/reference/clibrary/ctime/time/" rel="nofollow noreferrer">here</a></li> <li>you can use <a href="http://eigen.tuxfamily.org/dox-devel/QuickRefPage.html" rel="nofollow noreferrer">eigen</a> for linear algebra. It's an amazing library, I'm in love with it.</li> <li>check <a href="http://www.cplusplus.com/doc/tutorial/files/" rel="nofollow noreferrer">here</a> to learn how to manipulate files</li> </ul> <p>While using C++, you might miss some features from python, but most of them are actually provided by the <a href="http://www.boost.org/" rel="nofollow noreferrer">boost</a> libraries. For instance returning multiple values from a function is very easy with <a href="http://www.boost.org/doc/libs/1_49_0/libs/tuple/doc/tuple_users_guide.html" rel="nofollow noreferrer">boost.tuple</a> library as in <a href="http://www.boost.org/doc/libs/1_49_0/libs/tuple/doc/tuple_users_guide.html#tiers" rel="nofollow noreferrer">here</a>. You can use <a href="http://www.boost.org/doc/libs/1_49_0/libs/smart_ptr/shared_ptr.htm" rel="nofollow noreferrer">boost::shared_ptr</a> if you don't want to bother yourself with memory management. Or if you want to keep using python to play with your c++ classes, you can use <a href="http://www.boost.org/doc/libs/1_49_0/libs/python/doc/" rel="nofollow noreferrer">boost.python</a>. <a href="http://www.boost.org/doc/libs/1_49_0/libs/parameter/doc/html/index.html" rel="nofollow noreferrer">Boost.parameter</a> helps you define functions with named arguments. There is also <a href="http://www.boost.org/doc/libs/1_49_0/doc/html/lambda.html" rel="nofollow noreferrer">Boost.lambda</a> for lambda functions, but if your environment supports it, you can also use C++11 to have language support for lambda functions. Boost is a gold mine, never stop digging. Just assume that it's part of the standard library. I develop C++ in many different platforms, and neither eigen nor boost has let me down yet.</p> <p><a href="https://web.archive.org/web/20150519045338/http://www.parashift.com/c++-faq-lite/" rel="nofollow noreferrer">Here</a>'s a good FAQ for C++ best practices. <a href="http://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization" rel="nofollow noreferrer">This</a> is a very important principle that you have to keep in mind at all times, while working in C++. I extend it a bit, in my mind and think; If you're going to do something dangerous such as: Allocate memory with a raw <code>new</code>, or index a raw C style array, pass around raw pointers, or do <code>static_cast</code> (even worse <code>reinterpret_cast</code>) etc. They should usually happen in a class somehow dedicated to them, and the code to make sure they don't cause trouble lives very close to them, so that you can see at a glance that everything is under control.</p> <p>Finally, my favourite!!! Do you want to keep using generators in C++? <a href="http://www.codeproject.com/Articles/29524/Generators-in-C" rel="nofollow noreferrer">Here</a>'s some dark magic.</p>
