Template parameter deduction is the facility whereby the compiler determines how to instantiate a template when a template parameter is unspecified, e.g: 1. 2. std::vector<int> vi; std::sort(vi.begin(), vi.end()); Although we aren't specifying the type of iterator for std::sort () to use, the compiler works it out from the parameters we provide.Are you tired of using the same old PowerPoint templates for your presentations?

Containers and Algorithms (which you'll find very useful, unless you're hellbent on reinventing the wheel) are implemented as class templates and function templates, respectively. Unless a call is to a function template explicit specialization or to a member function of an explicitly specialized class template, a default argument for a function template or a member function of a class template is implicitly instantiated when the function is called in a context that requires the value of the default argument. They are implemented as class templates, which allows a great flexibility in the types supported as elements. The container manages the storage space for its elements and provides member functions to access them, either directly or through iterators (reference objects with similar properties to pointers). 18 May 2020 ...
