C++ :: Set Array Size At Compile Time Through Constructor

How do I set the size of a member array via the class constructor if I know the size at compile time. I can do this with templates, see below, but this leads to code bloats, I think.

So one class declaration but objects with different array sizes.

Can't use constexpr.
Can't use STL.
Can't use new.

#include <iostream>
using namespace std;
template<int T>
class MyArray {
private:
int array[T];
public:
int getSize()

[Code] ....
