Example

int main( )

{

double wholesale_cost, retail_price;

int shelf_time;

introduction( ); //fully tested

get_input(wholesale_cost, shelf_time); //fully tested

retail_price = price(wholesale_cost, shelf_time);//stubbed out

give_output(wholesale_cost, shelf_time, retail_price);//being tested

return 0;

}

//Uses iostream:

void give_output(double cost, int turnover, double price)

{

using namespace std;

cout.setf(ios::fixed);

cout.setf(ios::showpoint);

cout.precision(2);

cout << "Wholesale cost = $" << cost << endl

<< "Expected time until sold = "

<< turnover << " days" << endl

<< "Retail price= $" << price << endl;

}

//This is only a stub:

double price(double cost, int turnover)

{

return 9.99; //Not correct, but good enough for some testing.

}
