Question

This is the question of the textbook an introduction to programming with C++, 8th edition.

16. In this exercise, you will modify the tip program shown earlier in Figure 7-31. Follow the instructions for starting C++ and viewing the ModifyThis16.cpp file, which is con- tained in either the Cpp8\Chap07\ModifyThis16 Project folder or the Cpp8\Chap07 folder. (You may need to open the project/solution file first.) Change the for statement to a while statement. Save and then run the program. Test the program using 90.50 as the restaurant bill. The three tips should appear as shown earlier in Figure 7-32.

Answer 1

#include<iostream>

using namespace std;

int main()
{
   double bill = 0.0;
   
   double tip = 0.0;
   
   cout << "Bill amount: ";
   cin >> bill;//Input bill from the user
   
   double rate = 0.1;
   while(rate <= 0.2)
   {
      tip = bill * rate;
      
      cout << rate * 100 << "% tip: ";
      cout << "$" << tip << endl;
      rate += 0.05;
   }  //end while
   system("pause");
   return 0;
}
