This lab lets students work with the switch statement.
Copy and paste the code below in a filename LastFirst_lab44.cpp (e.g. DoeJoe_lab44.cpp) and save it in Lab 4 folder.
Bring in the LastFirst_lab44.cpp program from the Lab 4 folder.
Remove the break statements from each of the cases. What is the effect on the execution of the program?
Add an additional switch statement that allows for a Passing option for a grade of D or better. Use the sample run given below to model your output.
Sample Run: What grade did you earn in Programming I ? A YOU PASSED! an A - excellent work!
Rewrite the program LastFirst_lab44.cpp using if and else if statements rather than a switch statement. Did you use a trailing else in your new version? If so, what did it correspond to in the original program with the switch statement?
Submit the revised LastFirst_lab44.cpp
The following is the code to be used:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

// This program illustrates the use of the Switch statement.
// PLACE YOUR NAME HERE
#include <iostream>
using namespace std;
int main()
{
char grade;
cout << "What grade did you earn in Programming I ?" << endl;
cin >> grade;
switch( grade ) // This is where the switch statement begins
{
case 'A': cout << "an A - excellent work !" << endl;
break;
case 'B': cout << "you got a B - good job" << endl;
break;
case 'C': cout << "earning a C is satisfactory" << endl;
break;
case 'D': cout << "while D is passing, there is a problem" << endl;
break;
case 'F': cout << "you failed - better luck next time" << endl;
break;
default: cout << "You did not enter an A, B, C, D, or F" << endl;
}
return 0;
