constructor - C++ unexpected syntax errors -

ok have updated code:

#ifndef vector_h #define vector_h #include<cstdlib> #include<vector> #include<iostream> using namespace std; template < typename t> class myclass { public:     myclass() : size(10), index(0) { vec = new t[10]; };     myclass(int i) : size(i), index(0) { vec = new t[i]; };     friend bool add(t i);     virtual ~myclass();     friend ostream& operator<<(ostream& out, const t& obj);  private:     t * vec;     int size;     int index; }; template <typename t> virtual myclass<t>::~myclass() {     delete[] vec; } template <typename t> ostream& operator<<(ostream& out, const myclass<t>& obj){     (int = 0; < index; ++i)         out << obj[i] << " ";     out << endl; } template <typename t> bool myclass<t>::add(t i){     if (size == index){         size *= 2;         realloc(vec, size);     }     vec[index++] = i; } #endif // !vector_h 

error list: error 1 error c2039: 'add' : not member of 'myclass' c:\users\mihaibogdan\documents\visual studio 2013\projects\dashit\dashit\header.h 41

you should use qualified names

friend std::ostream& operator<<( std::ostream& out, const t& obj); 

standard c++ names declared in name space std.

otherwise compiler looks unqualified name ostream in global name space not of course declared.
