The idea of template specialization is to override the default template implementation to handle a particular type in a different way. For instance, while most vectors might be implemented as arrays of the given type, you might decide to save some memory and implement vectors of bools as a ...
——任意类(模板或非模板)可以拥有本身为类模板或函数模板的成员,这种成员称为成员模板(member template),成员模板不能为虚。 第六节:模板特化 ——模板特化是指一个或多个模板形参的实际类型或实际值是指定的。 @学习摘录197:模板特化转换方式 ——template <> int compare <const char*> (const char* const...

什么是特化(Specialization)和偏特化(Partial Specialization)?它们有什么作用? 请解释一下typename关键字在模板中的作用。 为什么要使用std::enable_if和SFINAE(Substitution Failure Is Not An Error)技术? 解释一下C++17引入的变量模板(Variable Template)。 什么是类型萃取(Type Traits)?举例说明如何使用类型萃取。
