b. Modify the program written for Exercise 9a to determine wener e eReTeO evenly divisible by a user-specified value, with no remainder. That is, is it evenly divisible by 3, 7, 13, or any other user-specified value? 10. (Data processing) As a part-time student, you took two courses last term. Write, run, and test a C++ program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for cach course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less than 2.0 and a congratulatory message if the GPA is 3.5 or above. cress. Except at e temperature and i ee different tempe /s2

Answer 1

The solution to the above question is given below with screenshot of output.

=====================================================

I kept the logic simple and i have tested all outputs.

I Have added comments in program so that it can be easily

understood.

If there is anything else do let me know in comments.

============ CODE TO COPY ===============================

main.cpp

#include <iostream>
using namespace std;

int main()
{
  // Variable for storing grades
  string  grade1 , grade2 ;

  // Variable for storing credits
  int     credit1, credit2;

  // Variable for storing GPA
  double  GPA = 0;

  cout << "Enter Grade For Course 1 : ";
  cin  >> grade1;

  cout << "Enter Credit For Course 1 : ";
  cin  >> credit1;
 
  cout << endl;

  cout << "Enter Grade For Course 2 : ";
  cin  >> grade2;

  cout << "Enter Credit For Course 2 : ";
  cin  >> credit2;

  // GPA FOR COURSE 1
  if ( grade1 == "A" )
    GPA = GPA + 4 * credit1;
  else if ( grade1 == "B")
    GPA = GPA + 3 * credit1;
  else if ( grade1 == "C")
    GPA = GPA + 2 * credit1;
  else if ( grade1 == "D")
    GPA = GPA + 1 * credit1;
  else
    GPA = GPA + 0 * credit1;

  // GPA FOR COURSE 2
  if ( grade2 == "A" )
    GPA = GPA + 4 * credit2;
  else if ( grade2 == "B")
    GPA = GPA + 3 * credit2;
  else if ( grade2 == "C")
    GPA = GPA + 2 * credit2;
  else if ( grade2 == "D")
    GPA = GPA + 1 * credit2;
  else
    GPA = GPA + 0 * credit2;

  cout << endl;

  // Average 
  GPA = GPA /  2 ;

  if ( GPA < 2.0 )
    cout << "Your GPA is Less Than 2.0 : " << GPA << endl;
  else if ( GPA > 3.5 )
    cout << "Your GPA is Good  : " << GPA << endl;
  else
    cout << "Your GPA is  : " << GPA << endl;
  
  return 0;

}

=====================================================

Output :

2 :/main Enter Grade For Course 1 : B Enter Credit For Course 1 : 2 Enter Grade For Course 2 : A Enter Credit For Course 2 : 1 : 5 Your GPA is Good
