C#
n Chapter 6, you continued to modify the GreenvilleRevenue program. Now, modify the program so that the major functions appear in the following individual methods:
GetContestantNumber - This method gets and returns a valid number of contestants and is called twice once for last year’s number of contestants and once for this year’s value
DisplayRelationship - This method accepts the number of contestants this year and last year and displays one of the three messages that describes the relationship between the two contestant values
GetContestantData - This method fills the array of competitors and their talent codes
GetLists - This method continuously prompts for talent codes and displays contestants with the corresponding talent until a sentinel value is entered
An example of the program is shown below:
Enter number of contestants last year >> 2 Enter number of contestants this year >> 3 Last year's competition had 2 contestants, and this year's has 3 contestants…

- True or FalseA value-returning method must contain a return statement.arrow_forwardOBJECT: To compute the net pay of an employee, given his/her pay rate, number of hours, and tax rate. INPUT: his/her name, pay rate, and number of hours. You will prompt the user with a friendly message to enter the employee’s name, pay rate and number of hours. Note that you must use the dash (-) to connect the first name to the last name so that the name can be read using the cin statement. For example, John-Doe OUTPUT: the employee’s gross pay, tax deduction, and net pay. For example: Name: John-Doe Your gross pay is: 900.00 Your tax deduction is: 90.00 Your net pay is: 810.00 METHOD: the gross pay is the pay rate times the number of hours. The tax deduction is computed as follows: If the gross pay is less than 1000.00, it is 10% of the total pay; otherwise, it is 15% of the gross pay. The net pay is the gross pay minus the tax deduction.

- 4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice.

- Problem Description: In the Whimsical Library, each book is enchanted with a magical code to ensure the protection of knowledge. The validation process for these magical codes involves a combination of mathematical spells. The validation process is described as follows: Take the sum of the digits at odd positions from left to right. Take the sum of the squared digits at even positions from left to right. If the absolute difference between the results from step 1 and step 2 is a prime number, the book code is considered valid; otherwise, it is invalid. Example 1: Consider the magical book code 86420137. Step 1. Take the sum of the digits at odd positions from left to right. 8+4+0+3=15 Step 2. Take the sum of the squared digits at even positions from left to right. 6^2+2^2+1^2+7^2=36+4+1+49 = 90 Step 3. If the absolute difference between the results from step 1 and step 2 is a prime number. 115-901 75 (not a prime number) Book code 86420137 is invalid.

The trick with multiple units of measure like this is to start with the largest unit (hours) and work down.
