Active code bases grow. The more developers working on a code base, the larger the code base becomes. We need abstractions such as functions, classes, data structures, layers and so on in order to manage the complexity of a large-scale code base. But constantly adding abstractions and new levels of indirection comes at a price — efficiency. This is where zero-cost abstractions plays its role. A lot of the abstractions offered by C++ comes at a very low price. At a minimum, C++ offers efficient alternatives at hot spots where performance really is a concern.
With C++ you are free to talk about memory addresses and other computer related low-level terms when needed. However, in a large-scale software project it is desirable ...
