I am trying to learn about templates, I want my class pair to be able to hold two objects of any type. I just want to provide an accessor function for obj1 now. But I get the following error when I try to complile:
error: expected initializer before '<' token T1 pair<T1,T2>::getObj1() My code is:
#include <iostream> #include <stdio.h> #include <string.h> using namespace std; template <class T1, class T2> class pair { public: pair(const T1& t1, const T2& t2) : obj1(t1), obj2(t2){}; T1 getObj1(); private: T1 obj1; T2 obj2; }; template <class T1, class T2> T1 pair<T1,T2>::getObj1() { return obj1; } int main() { return 0; } 1 Answer
pair is name of a standard class and with the using namespace std, there is a collision.
Several solutions :
- Rename your class to something else.
- Dont use the using statement
