Template class with variable parameters.

Suppose I have a template class:

Code:

---

template<class A, int B>
class foo
{
.....
}

---

is it possible to instantiate the template class with a variable in the second paramter?
int variable=99;
foo<apples, variable> foo1=new foo();
, where apples is a class.

My compiler doesn't let me do it as above; it requires the second parameter to be a constant.

Thanks.

It must be a compile-time constant. Templates are resolved at compile time. A different class foo is created for each different set of parameters you give it, so the compiler must know the parameter values when it is compiling.

I do not think so, since the template must be instantiated at compile type, and a variable's value may be determined at runtime.
