Vector and unspecialized class template

[Ek.H]

Hey,

I have a templated class (code follows) that I wish to put
into a vector, however I wish to put multiple of the class
into the vector and all might vary in what type they
represent.

Is there a way for me to to this without using multiple
vectors for each type of the class ?

(PS: I'm new to programming)
Code Snippet:

#include <iostream>
#include <vector>

template <typename Tclass keeper {
private:
T& value;
public:
keeper(T& in_value) : value(in_value) {
}

~keeper () {
}
};

int main () {

float my_float_value = 0.1f;
int my_int_value = 129;

keeper<floatmy_float(my_float_value);
keeper<intmy_int(my_int_value);

/* this one needs to be changed */
std::vector< keeper my_keepers;

return(0);
}

A standard vector is a template whose first argument is a class.
As soon as you try instantiating a vector, you need to provide
a *single* *complete* class. There can be no "multiple". Such
is the rule.

No.

However, if you want to keep different objects collected in
some kind of container, you should research "heterogeneous
container" on the web.

~keeper () {
}
};

int main () {

float my_float_value = 0.1f;
int my_int_value = 129;

keeper<floatmy_float(my_float_value);
keeper<intmy_int(my_int_value);

/* this one needs to be changed */
std::vector< keeper my_keepers;

return(0);
}

... What Victor said.

and

The way this is normally done is by storing pointers to a base class of
keeper<Tin the vector - or - by using an "any" class - like boost::any
or Austria C++ Any.
