return temp; }

void read_money(int& d, int& c) { cout << "Enter dollar "; cin >> d; cout << "Enter cents "; cin >> c; if( d < 0 || c < 0) { cout << "Invalid dollars and cents, negative values "; exit(1); } }

In this program the add is defined as a friend and has the type AltMoney as well.

Now, let's overload the "+" operator so that is does what the function add is doing.

Here are the changes that you need to make: (red font)

1) In class AltMoney: class AltMoney { public: AltMoney(); AltMoney(int d, int c);

friend AltMoney operator +(AltMoney m1, AltMoney m2); void display_money( ); private: int dollars; int cents; };

2) In the main:

sum = m1+m2;

3) In the function definition AltMoney operator +(AltMoney m1, AltMoney m2) { AltMoney temp; int extra = 0; temp.cents = m1.cents + m2.cents; if(temp.cents >=100){ temp.cents = temp.cents - 100; extra = 1; } temp.dollars = m1.dollars + m2.dollars + extra;

return temp; }

Here is what you need to do for the exercise:

Overload the % operator such that every time you use it, it takes two objects of type AltMoney as its arguments and returns: a) 5% of the difference between the income and expenditure, if income is larger than the expenditure b) -2% if the the expenditure is larger than the income. c) 0 if the expenditure is the same as income Note that, by doing this, you are required to overload the greater than sign (>), the smaller than sign (<), and the == sign.
