use only C# programming language

1. Write a method called DisplayPersonalInfo(). This method will display your name, school, program and your favorite course. Call the DisplayPersonalInfo() method from your program Main() method

2. Write a method called CalculateTuition(). This method will prompt the user for the number of courses that she is currently taking and then calculate and display the tuition cost. (cost = number of course * 569.99). Call the CalculateTuition() method two times from the same Main() method as in question 1.

3. Write a method call CalculateAreaOfCircle(). This method will prompt the user for the radius of a circle and then calculate and display the area.[A = πr²].
   Call the CalculateAreaOfCircle() method twice from the same Main() method as in question 1. Use Math.Pi for the value of π

4. Write a method call CalculateAreaOfTriangle(), that prompts the user for the base and height of a triangle and then calculate and display the area.[  ]
   Call the CalculateAreaOfTriangle() method twice from the same Main() method as in question 1.

5. Write a method call CalculateSaleCommission(), that prompts the user for his sales figure, and then calculate and display his commission. (commission = 25% of sales in excess of 1000. If sales is equal to or below $1000.00 there is no commission)
   Call the CalculateSaleCommission() method three times from the same Main() method as in question 1.

6. Write a method call DisplaySineTable(), that prompts the user for a starting value and an step size. The method will calculate and display a table (10 rows) of sine values based on the user input. Use the built-in method Math.Sin() to obtain the sine of an angle. e.g. if the starting value is 0.5 and the step size is 0.03 the method will display the following table:
   0.50 0.4794
   0.53 0.5055
   0.56 0.5311
   
   0.77 0.6961
   The numbers in both columns MUST be right aligned. Call the DisplaySineTable() method from the same Main() method as in question 1.

7. In a write a method called DisplayMenu() to display the following text on screen:

===========Narendra’s Computer Systems================
| 1. Display Personal Information |
| 2. Calculate Tuition |
| 3. Calculate Area Of A Circle |
| 4. Calculate The Area Of A Triangle |
| 5. Calculate Sales Commission |
| 6. Display Sine Table |

======================================================
Enter the number of your choice ->

1. Add another method called ShowMenu() to your project. This method will call the method in question 7 continuously until the user presses 0. (You will have to invoke the method in a loop body, read in the user input as well as check the input). You will need to hook up all the methods that you wrote previously i.e. questions 1 to 6. Replace all the code from your Main() method with a single call to the ShowMenu() method

1. Write a method called DisplayHorizontalStars(int numberOfStars). This method will output the number of stars horizontally specified by its argument. Call the DisplayHorizontalStars() method three times from your program Main() method, supplying 0, 5 and 10 respectively for the number of stars.

2. Write a method similar to the one above that displays a vertical line of stars.
   Call this method three times with arguments 0, 5 and 10 respectively.

3. Write a method that accepts an argument of type double. The method will calculate and display the volume of a sphere with radius specified by its argument. [ ].
   Call this method from your main three times, with arguments 1, 2, and 10 respectively. The answers are 4.1888, 33.5103 and 4188.7902 respectively.
   Use Math.PI for the value of 

4. Write a method that takes two arguments: a cost price and a two-letter province code. It will calculate and display the selling price. (If province is Ontario a tax of 13% is added to the price, if the province is Quebec a tax of 17% is added to the cost price. There is no tax for the rest of the provinces and territories).
   In your main, call this method enough times to fully test it

5. Write a method that takes a single argument of type double. The will display a Celsius to Fahrenheit conversion table. The starting temperature is indicated by the argument and it will display 10 lines in increments of 1. [Fahrenheit = 9/5 Celsius + 32].
   In your main call this method two times, each time with a different start value.

6. Write a method that takes the following arguments: a starting km value of type double, an increment size of type double and the number of lines of type int. The display a kilometer to miles conversion table. [miles = km * 0.621371].
   In your main call this method three times, each time with different values.
