#Dynamic vector class + template

if you're mimicing std::vector vector<int> v(5) should initialize it with 5 elements, so create a constructor that takes a std::size_t as argument

if you're mimicing `std::vector` `vector<int> v(5)` should initialize it with 5 ...
but that's what I did
pastel quartz
what error are you getting?
nocturne verge
where? you have a constructor taking a vector and an int?
pastel quartz
but that's what I did
the std::vector constructor sets the size, not the capacity
nocturne verge
ah + more
probably linker errors
assuming he defined the functions in a .cpp file
pastel quartz
- more?

And notice that Vector<T>& is the same as simply Vector&
pastel quartz
Does that work in the first Vector<T> of the definition too?

@brave chasm why are you passing vector as a argument in parameterized constructor?

No idea what it was anymore
pastel quartz
Vector<T>::Vector(etc etc)
rugged jolt
Vector<T>::Vector(etc etc)
Ah no in that scenario you can’t just do Vector::Vector
It was meant more for parameters, Vector(const Vector<T>& rhs);
Well actually I am not sure that that would be considered a copy constructor at all even if T of rhs equals the current T
Vector(const Vector& rhs) clearly would
;compile -std=c++20
#include <type_traits>
#include <iostream>
template<class T>
struct Foo {
Foo(const Foo<T>& other) = delete;
private:
// Foo(const Foo& other) {}
};
int main(){
std::cout << std::is_copy_constructible<Foo<int>>::value;
}
