Since the variables are private than why it show no error on compiling because we call a private members (highlighted) from another class. i know about get and set but here we use get set only for private string courseName.
using System;
public class GradeBook
{
private string courseName;
private int total;
private int gradeCounter;
private int aCount;
private int bCount;
private int cCount;
private int dCount;
private int fCount;
public string CourseName
{
get
{
return courseName;
}
set
{
courseName = value;
}
}
public GradeBook(string name)
{
CourseName = name;
}
public void DisplayMessage()
{
Console.WriteLine("Welcome to the {0}",CourseName);
}
public void InputGrade()
{
int grade;
string input;
Console.WriteLine("{0}\n{1}","Enter the grade in the Range (0-100): ", "Type ctrl+z and press enter to terminate the input");
input=Console.ReadLine();
while(input !=null)
{
grade = Convert.ToInt32(input);
total += grade;
gradeCounter++;
IncreamentLetterGradeCounter(grade);
input = Console.ReadLine();
}
}
private void IncreamentLetterGradeCounter(int grade)
{
switch(grade/10)
{
case 9:
case 10:
aCount++;
break;
case 8:
bCount++;
break;
case 7:
cCount++;
break;
case 6:
dCount++;
break;
default:
fCount++;
break;
}//end of switch
}//end of method increament letter grade counter
public void DisplayGradeReport()
{
Console.WriteLine("Grade Report: ");
if (gradeCounter != 0)
{
double average = (double)(total / gradeCounter);
Console.WriteLine("Total of the {0} grades enter is {1}", gradeCounter, total);
Console.WriteLine("The average of class is {0:F2}", average);
Console.WriteLine("{0}A: {1}\nB: {2}\nC: {3}\nD: {4}\nF: {5}", "Number of students who recieved each grade: \n"
, aCount
, bCount
, cCount
, dCount
, fCount);
}
else
Console.WriteLine("No grades were entered");
}
}
#####ANOTHER CLASS#########
using System;
class GrdaeBookTest
{
public static void Main()
{
GradeBook myBook = new GradeBook("Introduction to C#");
myBook.DisplayMessage();
myBook.InputGrade();
myBook.DisplayGradeReport();
Console.ReadLine();
}
}
