It is allowed, however, you can no longer to use un-specialized member function.
using namespace std;
template <typename T>
class myTemplate
{
public:
void Foo1(){cout<<"Foo1"<<endl;}
void Foo2(){cout<<"Foo2"<<endl;}
};
template <>
class myTemplate<float>
{
public:
void Foo1(){cout<<"Float Foo1"<<endl;}
};
int main()
{
myTemplate<int> i;
i.Foo1();
i.Foo2();
myTemplate<float> f;
f.Foo1();
//f.Foo2(); //error C2039: 'Foo2' : is not a member of 'myTemplate<float>'
return 10;
}
