template function and vector accessing

Design problem- one function calls all three

I continuation from another question after that thread, here is what I try:

template<class T>
void func(T* p)
{
   p->
}

I am stuck after that arrow as I don't know how to access each element of the which vector I passed in? The func receives argument as a switch case, I have solved it but the code inside all repeated except the vector. :-(

I am new about template, please help me.

Thank you.

template<class T>
void func(T*p)
{
   (*p)[0]; // the first element of the passed-in vector (or array)
}
