error C2955: use of class template requires template argument list in C++/MFC

[mfcdoubt]

I have following header file defines

test2.h ----------> header file

template<class T>
class temp2
{
public:
temp2();
virtual ~temp2();
};

test1.h ----------> header file

template<class T>
class temp1
{
public:
temp1(temp2<T> (temp2<T> *temp2ptr);
~temp1(temp2<T> ();

protected:
temp2<T> *tempptr;

};

test3.h -------------> header file
class test3
{
public:
test3();
virtual ~test3();

};

template<class T> temp1<T>::temp1(temp2<T> *temp2ptr)
{
tempptr = temp2ptr;
}

main.h ----------> header file

temp1 *maintemp1;
temp2<test3> maintemp2;

and in main.cpp -------> source file I am creating an object for this like given below

maintemp1 = new temp1(&maintemp2);

Now when I compile I am getting error

error C2955: 'temp1' : use of class template requires template argument list

can any body tell me what is the wrong with my code block ..

temp1 *maintemp1;

temp1 is a template class. The error means exactly what it says, and you should add a template argument list. Maybe temp1<test3> ?

Hi,
Thank for your quick response, I changed my code block as you told

temp1<test3> maintemp1;
temp2<test3> maintemp2;

and in main.cpp -------> source file I am creating an object for this like given below

maintemp1 = new temp1(&maintemp2);

But still I am getting the same error as above

I am sorry, I should have been more specific. Change the name everywhere. Your compiler should be giving you line numbers in the error, so you can find where you need to make changes. In the code you posted, maintemp1 = new temp1(&maintemp2); will not work for the same reason. temp1 is a template and needs a list of template arguments:

maintemp1 = new temp1<test3>(&maintemp2);

Every time you use the name of a template, you need to provide a template argument list too.

Perfect It worked .. Thank you very much for your help

public:
    mypair(T first,T second){a= first; b=second;}
    T getmin();
};
template < class T >
T mypair::getmin(){ T retval;
retval=a<b?a:b;
return retval;}
void main(){
    mypair <int>myobject(100,75);
    cout<<myobject.getmin()<<endl;}

i don't now why i have this erorr :error C2955: 'mypair' : use of class template requires template argument list
