Sometimes, you need to customize the behavior of a template for a specific type. This is calledtemplate specialization. Example: Specialization of Function Templates This example demonstrates how to specialize a function template for a specific data type. The generic template handles most types, while...

For example: #include <iostream> template <typename T> T addOne(T x) { return x + 1; } int main() { std::cout << addOne("Hello, world!") << '\n'; return 0; } Copy In this example, we’re calling addOne() on a C-style string literal. What does that actually mean sem...
For example:C++ Copy // function_templates2.cpp template<class T> void f(T) {} int main(int j) { f<char>(j); // Generate the specialization f(char). // If not explicitly specified, f(int) would be deduced. } When the template argument is explicitly specified, normal implicit ...
【C++】member template function 成员模板函数 It is also possible to define a member template function. Let's look at an example and then walk through it: classPrintIt{public:PrintIt(ostream&os) : _os( os ){}//a member template functiontemplate<typenameelemType>voidprint(constelemType&elem,...
template <animal Animal> void give_head_scratches (Animal const& the_animal); This is quite verbose and repetitive. Ideally we’d be able to use the concept name directly in the function parameter list like this: Copy void give_head_scratches (animal const& the_animal); ...
