A trailing template-argument can be left unspecified in an explicit instantiation of a function template specialization or of a member function template specialization if it can be deduced from the function par
template <typename... Ts> // typename... refers to zero or more template parameters, where the three dots "..." is called pack in cppreference (https://en.cppreference.com/w/cpp/language/pack). It coud also be used in the definition of function. struct IsAllIntegral { static const...

An explicit object parameter cannot be a function parameter pack, and it can only appear as the first parameter of the parameter list in the following declarations: a declaration of a member function or member function template an explicit instantiation or explicit specialization of a templated ...
Function Template Specialization-: #include <iostream> using namespace std; template <class T> void fun(T a) { cout << "The main template fun(): " << a << endl; } template<> void fun(int a) { cout << "Specialized Template for int type: " << a << endl; } int main() {...
Partial Template Specialization 顾名思义,模版偏特化就是对模版进行特化的意思。 举个例子: namespaceSHFTest { template< classPLA, classPLB > classPLClass { // //一般实现 // public: PLClass() {}; ~PLClass() {}; voidFuncA() {
