Chris Johanson wants a program that calculates and displays a 10%, 15%, and 20% tip on his total restaurant bill. First, create an IPO chart for this problem, and then desk-check the algorithm twice, using $35.80 and $56.78 as the total bill. After desk-checking the algorithm, list the input, processing, and output items in a chart similar to the one shown in Figure 3-23, and then enter the appropriate C++ declaration statements.  



ANSWER

Program to calculate tip for the total bill.

#include
using namespace std;

int main() 
    //reading inputs
    double cupPrice,platePrice,cupsPurchased,platesPurchased,salesTax,totalBill;
    cout
    cin>>cupPrice;
    cout
    cin>>platePrice;
    cout
    cin>>cupsPurchased;
    cout
    cin>>platesPurchased;
    cout
    cin>>salesTax;
    cout
    cin>>totalBill;
    
    // processing
    double finalCost = (cupPrice*cupsPurchased)+(platePrice*platesPurchased)+totalBill;
    finalCost = finalCost + (finalCost*salesTax*0.01);
    //printing tips
    cout<><>
    cout<><>
    cout<><>
    return 0;
