void Ledger::PrintPurchases() { unsigned int i; Purchase currPurchase;

for (i = 0; i

int main() { Ledger ledger;

ledger.InputPurchases(); ledger.PrintPurchases(); return 0; }

Write the InputPurchases() function in the Ledger class. Within InputPurchases(), use currPurchase's ReadFoodAndQuantity() to read each pair of inputs, string food and integer quantity, until "end" is read from input and currPurchase's ReadFoodAndQuantity() returns false. If currPurchase's ReadFoodAndQuantity() returns true, append currPurchase to vector purchaseList. Ex: If the input is truffle 3 cabbage 20 pumpkin 7 end, then the output is: Purchase: truffle, Quantity: 3 Purchase: cabbage, Quantity: 20 Purchase: pumpkin, Quantity: 7
