myclass is a C++ class written by me and when I write: myclass x; cout &lt;&lt; x; How do I output 10 or 20.2, like an integer or a float value?

template <class T> std::shared_ptr<MyClass<T>> MyClass<T>::MyFunction(const MyClass& a, const MyClass& b) { auto newObject = std::make_shared<MyClass<T>>(MyClass<T>(a.member, b.member2)); //...do stuff to the object return newObject; } This is the right way to do it in modern C++, if you ever think about returning pointers.

2010年6月2日 · Using div.myClass would be slower performance wise as opposed to just going .myClass. Always target an element directly when possible, this applies to everything. Rather than obtaining the parent element and then using that to target child elements which will impact performance always use ID's and classes when possible.

2016年1月15日 · I think the compiler just think myClass should be followed by <>, because it's a template. So said differently, the compiler can't find a non-template class named myClass . – songyuanyao

2017年5月2日 · private static List<MyClass> ListOfStoreObjects = new List<MyClass>(); My trouble is that I store the stuff into these lists and I can't remove them. I use those lists to store temporary data in a web service (I want to 'walk this way', so please don't tell me other solutions, thx) and of course, once those data were used I've to manage to ...
