C++ Type Inference
Introduction
This topic discusses about type inferencing that involves the keyword
auto type that is available from C++11.
Remarks
It is usually better to declare const, & and constexpr whenever you use auto if it is ever required to prevent unwanted behaviors such as copying or mutations. Those additional hints ensures that the compiler does not generate any other forms of inference. It is also not advisible to over use auto and should be used only when the actual declaration is very long, especially with STL templates.
