Coding in C# please 

• Using the code provided create the missing methods CalculateAverage() and ShowAverage() so they receive the arguments that are passed from the existing calling instructions. 

• Design CalculateAverage() so it returns the calculated average of equally weighted course grades. 

• Design ShowAverage() so the output displays the following: 

G. Treele average: 84

 

using System; namespace ConsoleApplication1 { class Program { } static void Main() { } const float MATH GRADE = 80.0f ; const float = 80.0f; const float PROGRAMMING GRADE = 92.0f; const string STUDENT_NAME BIOLOGY GRADE = "G. Treele"; // Call CalculateAverage () to calculate the average grade. float average = CalculateAverage (MATH_GRADE, BIOLOGY GRADE, // Call ShowAverage () to display the student name and overall average. ShowAverage (STUDENT_NAME, average); Console.ReadLine();
