class InventoryTag {
public:
InventoryTag();
int getQuantityRemaining() const;
void addInventory(int numItems);

int quantityRemaining;
};

InventoryTag::InventoryTag() {
quantityRemaining = 0;
}

int InventoryTag::getQuantityRemaining() const {
return quantityRemaining;
}

void InventoryTag::addInventory(int numItems) {
if (numItems > 10) {
quantityRemaining = quantityRemaining + numItems;
}
}

int main() {
InventoryTag redSweater;
int sweaterShipment = 0;
int sweaterInventoryBefore = 0;

sweaterInventoryBefore = redSweater.getQuantityRemaining();
sweaterShipment = 25;

cout << "Beginning tests." << endl;

// FIXME add unit test for addInventory

Explanation / Answer

#include <iostream>
using namespace std;

class InventoryTag {
public:
InventoryTag();
int getQuantityRemaining() const;
void addInventory(int numItems);

private:
int quantityRemaining;
};

InventoryTag::InventoryTag() {
quantityRemaining = 0;
}

int InventoryTag::getQuantityRemaining() const {
return quantityRemaining;
}

void InventoryTag::addInventory(int numItems) {
if (numItems > 10) {
quantityRemaining = quantityRemaining + numItems;
}
}

int main() {
InventoryTag redSweater;
int sweaterShipment = 0;
int sweaterInventoryBefore = 0;

sweaterInventoryBefore = redSweater.getQuantityRemaining();
sweaterShipment = 25;

cout << "Beginning tests." << endl;

testAddInventory(redSweater,sweaterShipment);

cout << "Tests complete." << endl;

return 0;
}

void testAddInventory(InventoryTag redSweater,int sweaterShipment)

{

redsweater.addInventory(sweaterShipment);

int quantity=redsweater.getQuantityRemaining();

if(quantity != 25)

cout<<" UnNIT TEST FAILED:addInventory()";

}
