In the last post I wrote about how to change our code to avoid getting compiler warnings. Sometimes that is not a feasible approach and we need to tell your compiler […]
We often see compiler warnings about pieces of code that have potential problems or poor style. Sometimes they point out code that is actually wrong, so don’t ignore them.
Move constructors are often cheaper than copy constructors, which makes the construction and immediate relocation of objects in modern C++ more effective than in C++03. However, just moving the parts needed to construct the object in the right place can be even more effective. Several standard library functionalities use perfect forwarding to construct objects right where they are needed.
This is another post motivated by Twitter: It’s about those cheat sheets, for example those showing C++ operator precedence, that some people have stick to their monitor or cubicle wall. Unless they […]
