add a global function (not a member function of your class) called doPrint that accepts a Number and prints out its value followed by a newline.

code:

#include

using namespace std;

class Number{

public:

virtual double getValue() const = 0;

};

//Do not modify anything on or above the line below this

//YOUR_CODE_BELOW

//YOUR_CODE_HERE

//YOUR_CODE_ABOVE

//Do not modify anything on or below the line above this

class Int : public Number {

private:

int value;

public:

Int(int i) { value = i; }

double getValue() const { return value; }

};

class Double : public Number {

private:

double value;

public:

Double(double d) { value = d; }

double getValue() const { return value; }

};

int main()

{

Int n1(2);

Double n2(1.5);

doPrint(n1);

doPrint(n2);

}
