c++ - passing a dummy int int the template argument -


this question has answer here:

recently got stuck in templates , passed dummy argument in template isn't working , gives compilation error here code..

#include <iostream> using namespace std; template<typename t> class a{     private:         t b;     public:         a()         {             cout<<"1st executing "<<endl;         } }; template<typename t,int> class a{     private:         t b;     public:         a(){             cout<<"2nd executing "<<endl;         } }; int main(){     a<string> a;     a<string,100> b; }

in point of view should work fine gives re declaration error , dn't know why .....plz thanks

i'm not sure, think template <typename t = int>
