How do I do this WITHOUT the use of a \"USING\" statement or call to a writeline

Question

How do I do this WITHOUT the use of a "USING" statement or call to a writeline??

All answers so far have used both??

Code the Grades project from Exercise 3-1, such that you obtain exactly the same output, including formatting/positioning, WITHOUT including the "using" keyword OR any calls to Writeline.

HINT: "System.XYZ…." accesses class “XYZ” within the namespace “System”.

using System;

class Grades { public static void Main( string[] args)

{ const float MIDTERM_PERCENTAGE = .25F;

const float FINALEXAM_PERCENTAGE = .25F;

const float RESEARCH_PERCENTAGE = .30F;

const float PRESENTATION_PERCENTAGE = .20F;

int midterm = 70;

int finalExGrade = 80;

int research = 90;

int presentation = 100;

float finalNumericGrade = 0;

finalNumericGrade = (midterm * MIDTERM_PERCENTAGE) + (finalExamGrade * FINALEX_PERCENTAGE) + (research * RESEARCH_PERCENTAGE) + (presentation * PRESENTATION_PERCENTAGE);

Console.WriteLine(" Midterm grade is : " + midterm);

Console.WriteLine(" Final Ex grade is : " + finalExamGrade);

Console.WriteLine(" Research grade is : " + research);

Console.WriteLine(" Presentation grade is: " + presentation);

Console.WriteLine(" nThe final grade is: " + finalNumericGrade); } }

}

using System;

namespace UserDefined{

   class Display

   {

      public void func(str)

      {

         Console.WriteLine(str);

      }

   }

}

Explanation / Answer

From the question, I understand that instead of using built in function, you need to use the func() defind in Display() class in UserDefined namespace.

To do that,

1. Remove the using System; line before the class Grades

2. Use the following code for class Grades

class Grades {
public static void Main( string[] args)
{
const float MIDTERM_PERCENTAGE = .25F;
const float FINALEXAM_PERCENTAGE = .25F;
const float RESEARCH_PERCENTAGE = .30F;
const float PRESENTATION_PERCENTAGE = .20F;
int midterm = 70;
int finalExGrade = 80;
int research = 90;
int presentation = 100;
float finalNumericGrade = 0;
finalNumericGrade = (midterm * MIDTERM_PERCENTAGE) + (finalExamGrade * FINALEX_PERCENTAGE) + (research * RESEARCH_PERCENTAGE) + (presentation * PRESENTATION_PERCENTAGE);

UserDefined.Display.func(" Midterm grade is : " + midterm);
UserDefined.Display.func(" Final Ex grade is : " + finalExamGrade);
UserDefined.Display.func(" Research grade is : " + research);
UserDefined.Display.func(" Presentation grade is: " + presentation);
UserDefined.Display.func(" nThe final grade is: " + finalNumericGrade);
}
}

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

In the above code, we are calling the func() in class Display from namespace UserDefined. This is done as UserDefined.Display.func( ... )
