Answer 1

#include <stdio.h>

#define COFFEE_PRICE (1.75)

#define TEA_PRICE (1.50)

#define SALES_TAX (0.13)

typedef struct _THotDrinkOrder

{

char customerName[255];

int numCoffee;

int numTea;

} *THotDrinkOrder;

void InputHotDrinkOrder(THotDrinkOrder myHotDrinkOrder)

{

int numCoffee=-1;

int numTea=-1;

while (numCoffee<0)

{

printf(" How many coffee ???? :>");

scanf("%d",&numCoffee);

}

while (numTea<=0)

{

printf(" How many tea ??? :>");

scanf("%d",&numTea);

}

printf(" customer first name :>");

scanf("%s",myHotDrinkOrder->customerName);

myHotDrinkOrder->numCoffee = numCoffee;

myHotDrinkOrder->numTea = numTea;

}

void PrintReceipt(THotDrinkOrder myHotDrinkOrder)

{

printf("\n\n Hot Drink Order for Customer %s \n",myHotDrinkOrder->customerName);

printf("--------------------------------------------------------------\n");

double total=0;

double subtotal = myHotDrinkOrder->numCoffee*COFFEE_PRICE;

printf(" # of coffee : %d x $%6.2f = %6.2f \n",myHotDrinkOrder->numCoffee,COFFEE_PRICE,subtotal);

total += subtotal;

subtotal = myHotDrinkOrder->numTea * TEA_PRICE;

printf(" # of tea : %d x $%6.2f = %6.2f \n",myHotDrinkOrder->numTea,TEA_PRICE,subtotal);

total += subtotal;

printf("----------------------------------------------------------------\n");

printf(" SubTotal is %6.2f \n",total);

subtotal = total * SALES_TAX;

printf(" sales tax at %6.2f %% = %6.2f \n",SALES_TAX*100.0f,subtotal);

total += subtotal;

printf(" Your total is %6.2f \n",total);

printf(" Thank you for your business !!!!\n");

}

void Go()

{

struct _THotDrinkOrder myHotDrinkOrder;

InputHotDrinkOrder(&myHotDrinkOrder);
