you can instantiat a template in two ways. 1. Implicit instantiation and 2. Explicit Instantion. implicit instatanitioan can be done by the following ways:
template <class T>
class A
{
public:
A(){}
~A(){}
void x();
void z();
};
void main()
{
A<int> ai;
A<float> af;
}
External Instantion can be done the following way:
int main()
{
template class A<int>;
template class A<float>;
}
