Question

1. Declare/define the variable/constant as indicated: a. a variable to store the grade for a student (as whole number) b. a variable to store a letter grade for a course, like A, B, or C c. a variable to store an average for a student (may have decimal places) d. a variable to represent if a student passed the course or not, with a value of TRUE or FALSE e. a constant to represent the passing grade of 65 2. Using the variables declared above and any other you may need, write the program segment to  read 4 values into the student’s grade (using only the variable you declared in a. above), You will need to keep track of the sum as you read.  find the student’s average as a real number, to be stored in variable d above. Print the average  determine if the student passed and store that value in d. above, using the constant defined in e. above, and print an appropriate message

Answer 1

Since you haven't provided which language to use, I shall provide the code for both C++ and Java.

Java code:

import java.util.*;
import java.io.*;

class Main {
  static int value = 65;   // 1.(e)
        public static void main (String[] args) {
                double marks;  // 1.(a)
                char grade;   // 1.(b)
          double average;  // 1.(c)
                boolean pass;   // 1.(d)
                double sum = 0.0;
                
                Scanner sc = new Scanner(System.in);
                System.out.println("Enter grades:");
                int count=4;
                while(count-->0){
                    marks = sc.nextDouble();
                    sum = sum+marks;
                }
                average = sum/4;
                System.out.println("Student's average = "+ average);
                if(average>=value){
                    pass = true;
                    System.out.println("Congrats! You passed!");
                }else{
                    pass = false;
                    System.out.println("You failed!");
                }
        }
}

C++ code:

#include <iostream>
using namespace std;

    int main(){
                double marks;  // 1.(a)
                char grade;   // 1.(b)
            double average;  // 1.(c)
                bool pass;   // 1.(d)
                const int value = 65;   // 1.(e)
                double sum = 0.0;
                
                cout<<"Enter grades:"<<endl;
                int count=4;
                while(count-->0){
                    cin>>marks;
                    sum = sum+marks;
                }
                average = sum/4;
        cout<<"Studen't average = "<<average<<endl;
                if(average>=value){
                    pass = true;
                    cout<<"Congrats! You passed!"<<endl;
                }else{
                    pass = false;
                    cout<<"You failed!"<<endl;
                }
                return 0;
        }
