// Exercise 4.16: GradeConverter.cpp
// Input a numeric grade from the user and
// display the corresponding letter grade.
#include <iostream> // required to perform C++ stream I/O

using namespace std; // for accessing C++ Standard Library members

// function main begins program execution
int main()
{
   int grade; // define variable to store numeric grade

   // prompt user for and store input
   cout << "\nEnter numeric grade: ";
   cin >> grade;

   // display letter grade
   cout << "\nGrade is: ";

   if ( grade > 90 )
   {
      cout << "A" << endl;
   } // end if
   else if ( grade >= 80 )
   {
      cout << "B" << endl;
   } // end else if
   else if ( grade >= 70 )
   {
      cout << "C" << endl;
   } // end else if
   else if ( grade >= 60 )
   {
      cout << "D" << endl;
   } // end else if
   else
   {
      cout << "F" << endl;
   } // end else

   cout << "\n"; // insert newline for readability
   
   return 0; // indicate that program ended successfully

} // end function main
