C#

1. Create an Employee class with two fields: idNum and hourlyWage. The Employee constructor requires values for both fields. Upon construction, thrown an ArgumentException if the hourlyWage is less than 7.50 or more than 50.00. Write a program that establishes, one at a time, at least three Employees with hourlyWages that are above, below, and within the allowed range. Immediately after each instantiation attempt, handle any thrown Exceptions by displaying an error message. Save the file as EmployeeExceptionDemo.cs.

2. Write an application that creates an array of five Employees. Prompt the user for values for each field for each Employee. If the user enters improper or invalid data, handle any exceptions that are thrown by setting the Employee’s ID number to 999 and the Employee’s pay rate to the $7.50. At the end of the program, display all the entered, and possible corrected, records. Save the file as EmployeeExceptionDemo2.cs.

Leap year and Second in year program

1. Whether a year is a leap year on not a leap year.
2. The number of seconds in a year. (FYI, it will be a different amount for leap vs non-leap year.) You can calculate the seconds by whatever means you choose, whether with defined constants and calculations or just calculations. It is your choice.
3. If the user inputs a year number greater than zero, the program returns how many seconds were or will be in that year.
4. Put in descriptions for your request for input. If you do the bonus portion, also put that in for your request.
5. Tell the user that an input of -99 ends the program. (+5)
   Put your prompt in a loop, asking the user each time what year to check. (+5)
6. You should assume a day length of exactly 24 hours. Obviously, multiplying 365*24*3600 isn’t exactly a programming challenge, and it won’t even give the right answer for all years.
7. You must take account of leap years, which means your years will not all have the same number of days. If you do not already know, here is the calculation for leap years:

1. If a year is divisible by 4 with no remainder, it is a leap year,
2. unless it is a centurial year (ending in 00).
3. Then it is not a leap year,
4. unless it is a year divisible by 400, in which case it is still a leap year.

For example:

1904 is a leap year—evenly divisible by 4.
1900 is not a leap year—it is evenly divisible by 4, and also evenly divisible by 100. However, it is not evenly divisible by 400.
2000 is a leap year— it is evenly divisible by 4, evenly divisible by 100, but also evenly divisible by 400.
Your calculation should ignore all other variations in the length of the calendar year, such as leap seconds or the change from the Julian to the Gregorian system.

1. Draw the supply and demand graph for coffee below assuming the market operates at an equilibrium price of $2.40 and an equilibrium quantity of 5,000.
2. Assuming tea and coffee are substitutes, what will happen in the market for coffee if the price of tea increases? Show the effects on your market.
3. Based on this information, will producer surplus in the market for coffee increase or decrease? Explain.

Create a Stash class specifically for storing Rect objects and call it RectStash. Add a default constructor and a destructor to correctly initialize your RectStash class. Then write a program that will read several lines as input. Each line will contain 4 floats defining a 2D rectangle in the Rect format described above. Read the rectangles adding them to a RectStash object. Stop reading rectangles when your program loads 4 negative float values. After this point you will start reading a series of 2D points, and for each 2D point you will print the classification of each point in respect to all previously read rectangles. The classification should print "in" or "out" according to its result. Stop your program when you read vector (-99,-99).

Everything should be contained in one file. You may not assume the existance of any header files in your working directory.

Sample Input:

-5 -5 2.5 2.5
5 8 2 2
-1 -1 -1 -1
0 0
-4 -6
6 9
-99 -99

result:
