Answer 1

#include <iostream>

class Test {
public:
	Test(int x) : m(x) {}

	Test(const Test&) = delete;

	Test& operator=(const Test&) = delete;

	int m;
};

int main()
{
	Test t1(87), t2(72), t3(98);

	t1 = t2; // Error cannot be referenced -- it is a deleted function

	t3 = Test(t1); // Error cannot be referenced -- it is a deleted function

	return 0;
}
