Question

In C++ and input code using the template below

• Get a copy of the caseswitch.cpp.

  The purpose of the program is to demonstrate how to use Switch statement.

• Complete the for loop so that the program will ask the user for 6 input grades.
• Compile and run this C++ program. Use input value A, B, C, D, E, and F.
• Notice there is no output for B and E. Add cases for them.
  • B is "Good Work." Add a case for 'B'.
  • E is not a legal grade. Add a default case for all unrecognized grades that prints grade << " is not a legal grade.".

Answer 1

Code:

#include <iostream>
using namespace std;
int main()
{
char grade;

for (int i=1;i<=6;i++)
{
cout << "Please enter a character grade (A, B, C, D, or F): ";
cin >> grade;

switch (grade)
{
case 'A': cout << "Great work. " << endl;
break;

case 'B': cout << "Good work. " << endl;
break;

case 'C': cout << "Passing work. " << endl;
break;
case 'D':
case 'F': cout << "Unsatisfictory work. " << endl;
cout << "See your instructor." << endl;
break;

default:
cout << grade << " is not a legal grade." << endl;

} //end of switch statement

} //end of for loop
return 0;
}
// end program
