Question

Using C#:

• Create a "Grades" class with the private variables: double grade1, double grade2, double grade3, double grade4, double grade5.

• In the Main method, ask the user to enter the five grades.

• In the ToString() method of the Grades class, print out the mean average (Example: Average: 86).

• Also, in the ToString() method of the Grades class, print out the 5 grades that were entered from highest to lowest. For example, if the user entered: 100, 80, 90, 75, 95, the ToString() method would print out, “Grade 1: 100, Grade 4: 95, Grade 3: 90, Grade 2: 80, Grade 4: 75.”

Answer 1

Program:

using System;
namespace Marks
{
class Grades
{
private double grade1;
private double grade2;
private double grade3;
private double grade4;
private double grade5;
  
public void getGrades(double g1, double g2, double g3, double g4, double g5)
{
grade1=g1;
grade2=g2;
grade3=g3;
grade4=g4;
grade5=g5;
}
  
public void ToString()
{
double average=(grade1+grade2+grade3+grade4+grade5)/5;
Console.WriteLine("Average: "+average);
double[] a={grade1, grade2, grade3, grade4, grade5};
double[] b={grade1, grade2, grade3, grade4, grade5};
Array.Sort(b);
for(int i=4;i>=0;i--)
{
for(int j=0;j<5;j++)
{
if(a[i]==b[j])
{
Console.WriteLine("Grade "+(j+1)+": "+a[i]);
}
}
}
}
}
class GradesChecker
{
static void Main()
{
Grades g=new Grades();
Console.WriteLine("Enter the five grades");
double grade1=Convert.ToDouble(Console.ReadLine());
double grade2=Convert.ToDouble(Console.ReadLine());
double grade3=Convert.ToDouble(Console.ReadLine());
double grade4=Convert.ToDouble(Console.ReadLine());
double grade5=Convert.ToDouble(Console.ReadLine());
g.getGrades(grade1, grade2, grade3, grade4, grade5);
g.ToString();
}
}
}

Screenshot of the Code:

for(int i=4;i>=0; i--) { for(int j =0; j<5; j++) { if(a[i]==b[j]) { Console.WriteLine("Grade "+(j+1)+": "+a[i]); } } } class GradesChecker { static void Main() { Grades g=new Grades(); Console.WriteLine("Enter the five grades"); double grade1=Convert.ToDouble(Console.ReadLine()); double grade2=Convert.ToDouble(Console.ReadLine()); double grade3=Convert.ToDouble(Console.ReadLine()); double grade4=Convert.ToDouble(Console.ReadLine()); double grade5=Convert.ToDouble(Console.ReadLine()); g.getGrades (grade1, grade2, grade3, grade4, grade5); g.ToString(); } }

Output:

Enter the five grades 95 96 98 97 99 Average: 97 Grade 5: 99 Grade 3: 97 Grade 4: 98 Grade 2: 96 Grade 1: 95
