LAB 5.2 Working with do-while loop

Bring the program dowhile.cpp from the Lab 5 folder.

The code is shown below:

______________________________________________________________________________

// This program displays a hot beverage menu and prompts the user to

// make a selection. A switch statement determines which item the user

// has chosen. A do-while loop repeats until the user selects item E

// from the menu.

// PLACE YOUR NAME HERE

#include

#include

using namespace std;

int main()

{

// Fill in the code to define an integer variable called number,

// a floating point variable called cost,

// and a character variable called beverage

bool validBeverage;

cout

do

{

cout

// Fill in the code to read in beverage

switch(beverage)

{

case 'a':

case 'A':

case 'b':

case 'B':

case 'c':

case 'C':

case 'd':

case 'D': validBeverage = true;

break;

default: validBeverage = false;

}

if (validBeverage == true)

{

cout

// Fill in the code to read in number

}

// Fill in the code to begin a switch statement

// that is controlled by beverage

{

case 'a':

case 'A': cost = number * 1.0;

cout

break;

// Fill in the code to give the case for tea ( $0.75 a cup)

//Fill in the code to give the case for hot chocolate($1.25 a cup)

// Fill in the code to give the case for cappuccino ($2.50 a cup)

case 'e':

case 'E': cout

break;

default:cout

// indicating an invalid selection.

cout

}

} // Fill in the code to finish the do-while statement with the

// condition that beverage does not equal (E or e).

// Fill in the appropriate return statement

}

Exercise 1: Fill in the indicated code to complete the above program. Then compile and run the run the program several times with various inputs. Try all the possible relevant cases and record your results.

Sample Run:

Exercise 2: What do you think will happen if you do not enter A, B, C, D, or E? try running the program and inputting another letter.

Sample Run:

Exercise 3: Replace the line

if (validBeverage == true)

with the line

if(validBeverage)

and run the program again. Are there any differences in the execution of the program? Why or why not?
