. Create a generic collection that stores even numbers from 2 to 20.

Display only the first element of the List.

.Create a delegates that accepts a number from user and displays whether the number is even or odd.

1. Create a delegate that displays a message (" you are underage" ) if the user's age is less than 18 and (you qualify to be an adult") if the age is greater than 18.

Create a struct named Product where its fields are code, description, and price. 

1. Create a method named getCircleDiameter that takes a radius of double type as the parameter. The method should return the diameter of a circle. To compute the diameter of a circle, multiply the radius by 2.

2.Create a struct named Product where its fields are code, description, and price.

Create a class named Person with an instance variable named full_name. Declare one (1) constructor without a parameter and initialize the variable with a default value.

3.Create a class named Account with an instance variable named account_number. Make this class a member of the Accounts namespace.

1. Create a struct named Product where its fields are code, description, and price. 

)Write a program that generates a random number between 1 and 10 inclusive. Ask a user to guess the random number, then display a message indicating whether the user’s guess was too high, too low, or correct.

• The message “Sorry – your guess was too low!” should be displayed if the number entered by the user is lower than the random number generated

• The message “Sorry – your guess was too high!” should be displayed if the number entered by the user is higher than the random number generated.

• The message “Congratulations – your guess is correct!” should be displayed if the number entered by the user matched the random number generated.

The user is given up to 3 attempts to guess.

• If the user did not successfully guess the random number after 3 attempts, display: “The random number was X” (X is the random number).

• If the user successfully guesses the random number within 3 attempts, display: “You guessed the number on attempt number X” (X is the attempt count).

Given months and temperature (in ºC) data as shown in the code snippet below:

string[] month = { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul",

"Aug", "Sep", "Oct", "Nov", "Dec" };

double[] temperature = { 3.0, 5.6, 9.7, 13.8, 19.0, 24.5, 26.0, 25.0,

21.3, 14.6, 7.6, 2.8 };

a) Determine the temperature classification based on the table given.

Temperature Classification Temperature Range

Freezing < 0 ºC

Very Cold 0 ºC – 5.9 ºC

Cold 6 ºC – 9.9 ºC

Cool 10 ºC – 13.9 ºC

Mild 14 ºC – 17.9 ºC

Moderate 18 ºC – 22.9 ºC

Warm 23 ºC – 26.9 ºC

Very Warm 27 ºC – 29.9 ºC

Hot > 30 ºC

b) Determine the minimum and maximum value from the array of temperature

given. Subsequently, compute the average mark (rounded to 2 decimal

places).

Account numbers sometimes contain a check digit that is the result of a mathematical calculation. It is used to help ascertain whether the number is a valid one. Develop a simple C# application that asks a user to enter a four-digit account number and determines whether it is a valid number. The number is valid if the fourth digit is the remainder when the number represented by the first three digits of the four-digit number is divided by 7. For example, 7770 is valid, because 0 is the remainder when 777 is divided by 7.
