Question

If you execute the code shown below and the user enters the following sales amounts for Region 1: 25000, 30000, 10000, –1, then, the value stored in totRegSales when the inner loop ends will be __________.

int sales = 0;

int region = 1;

int totRegSales = 0;

while (region < 3)

{

   cout << "First sales amount for Region "

        << region << ": ";

   cin >> sales;

   while (sales > 0)

   {

      totRegSales = totRegSales + sales;

      cout << "Next sales amount for Region "

           << region << ": ";

      cin >> sales;

   } //end while

  

   cout << endl << "Region " << region << " sales: $"

        << totRegSales << endl << endl;

   region = region + 1;

   totRegSales = 0;

} //end while

cout << "End of program" << endl;

65000

55000

-1

0

Answer 1

#include<iostream>
using namespace std;
int main()
{
int sales = 0;
int region = 1;
int totRegSales = 0;
while (region < 3)
{
cout << "First sales amount for Region "
<< region << ": ";
cin >> sales; //for eg user enters 25000
while (sales > 0)
{
totRegSales = totRegSales + sales; //0+25000=25000
cout << "Next sales amount for Region "
<< region << ": ";
cin >> sales;// user enters 30000
//now sales>0
//toRegSales=25000+30000=55000
//now user enters sales=10000
//as sales>0
//toRegSales=55000+10000=65000
//now user enters sales=-1
//as sales<0 loop terminates
} //end while
//now after inner loop execution toRegSales=65000
cout << endl << "Region " << region << " sales: $"
<< totRegSales << endl << endl;
region = region + 1;
totRegSales = 0;
} //end while
cout << "End of program" << endl;
}

65000 is correct answer
