Question

Write a C++ program to tally up the total cost of a customer order for Roasterie coffee shop.

The coffee shop offers the following items on its menu:

• Coffee($2.5)

• Tea($2.25)

• Soda($1.85)

• Juice($2)

• Special Item(self defined price)

The program takes input from the user about all the items and amounts. Below is an example:

- Please input item number:

1. Tea 2. Soda 3. Juice 4. Special Item

- 1

- How many:

- 3

- Please input item number:

1. Tea 2. Soda 3. Juice 4. Special Item

- 2

- How many:

- 1

If Special Item is entered, the program should ask about the item name and item price:

- Please input item number:

1. Tea 2. Soda 3. Juice 4. Special Item

- 4

- Item Name:

- Cheesecake

- Price:

- 6

- How many:

- 2

If nothing is inputted, the program prints the summary of the order, and the total price:

- You ordered: 3 Tea, 1 Soda, 2 Cheesecake. Total cost: $20.6

Use Functions in your Project.

Answer 1

Answer :

#include <iostream>

#include<stdlib.h>

using namespace std;

void order();

int main() {

cout << "Welcome to Roasterie Coffee Shop\n";

order();

return 0;

}

void order() {

//declare all variables related to products and totalcost

int n,c_count=0,t_count=0,s_count=0,j_count=0,st_count=0;

float c_sum=0,t_sum =0,s_sum =0,j_sum =0,st_sum= 0,price;

char item[100];

do {

cout << "\nPlease input item number:\n" << "1. Coffee 2. Tea 3. Soda 4. Juice 5. Special Item\n";

cin>>n;

switch (n) {

//for coffee

case 1 : cout<<"How many:\n";

cin>>c_count;

c_sum = c_count *2.5;

break;

//for tea

case 2 : cout<<"How many:\n";

cin>>t_count;

t_sum = t_count *2.25;

break;

//for soda

case 3 : cout<<"How many:\n";

cin>>s_count;

s_sum = s_count *1.85;

break;

//for juice

case 4 : cout<<"How many:\n";

cin>>j_count;

j_sum = j_count *2;

break;

//for specific item

case 5 : cout<<"ItemName:\n";

cin>>item;

cout<<"Price:\n";

cin>>price;

cout<<"How many:\n";

cin>>st_count;

st_sum = st_count *price;

break;

//when none of the input is selected, print cost

default : cout<<"You ordered: " <<c_count << " Coffee, "<<t_count << " Tea, " <<s_count << " Soda, "<<j_count <<" Juice, "<<st_count << " Cheesecake.\n" <<" Total cost: " <<c_sum +t_sum +s_sum +j_sum +st_sum <<"\n";

exit(0);

}

} while(1);

}

Output :
