Unknown errors in a class with multiple constructors and deep copying

I do not understand why there how to make the program output zeros for b.print and the first c.print. Also why there is an error when the program finishes the last c.print.
I do not know how to fix the problem that is in my constructors in the Vector.cpp file.

please delete the duplicated post http://www.cplusplus.com/forum/general/244066/
¿what's pch.h?

Vector::Vector(int s) {

	entries = new int[s];
}

you didn't set `size' there

Vector::Vector(const Vector &other) {
	size = other.size;
	entries=(new int[*other.entries]);
}

that's not how you copy arrays, you are trying to access the first element (which may not exist)

¿what's supposed to happen? I've got

[]
[0 0 0]
[0 0 0]
Invalid position. Position does not exist
Invalid position. Position does not exist
[1 2 3]
[1 2 3]
[1 0 3]
[1 2 3]
[]
Invalid position. Position does not exist
[]
[]

after fixing the constructors


> entries = new int[s];
by the way, you aren't setting the elements there
you reserve the memory but don't put any content, so they can have anything when you try to print them.
