In C#, please?
Write a program named CheckMonth2 that prompts a user to enter a birth month and day.
Display an error message that says Invalid date if the month is invalid (not 1 through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between 1 and 29 for February).
If the month and day are valid, display them with a message. For example, if the month entered is 2, and the day entered is 17, the output should be 2/17 is a valid birthday.
Part A
Write an application called ShadyRestRoom for the Shady Rest Hotel; the program determines the price of a room. Ask the user to choose 1 for a queen bed, 2 for a king, or 3 for a king and a pullout couch. The output echoes the input and displays the price of the room: $125 for queen, $139 for king, and $165 for a suite with a king bed and a pullout couch. If the user enters an invalid code, display an appropriate message and set the price to 0.
An example of the program is shown below:
Menu (1) Queen bed (2) King bed (3) Suite with a king bed and pull-out couch Enter Selection (1, 2, or 3) >> 2 You selected King bed $139
Part B
Copy the contents of the ShadyRestRoom application into ShadyRestRoom2.java file and rename the class ShadyRestRoom2. Add a prompt to the ShadyRestRoom application to ask the user to specify a (1) lake view or a (2) park view, but ask that question only if the bed size entry is valid. Add $15 to the price of any room with a lake view. If the view…
Assume that the population of Mexico is 128 million and the population of the United States is 323 million. Write a program called Population that accepts two values from a user: an assumption of an annual increase in the population of Mexico and an assumption for an annual decrease in the U.S. population. Accept both figures as percentages; in other words, a 1.5 percent decrease is entered as 0.015. Write an application that displays the populations of the two countries every year until the population of Mexico exceeds that of the United States, and display the number of years it took.
An example of the program is shown below:
Enter the percent annual increase for Mexico population
Enter as a decimal.
For example, 0.5% is entered as 0.005 Enter the value >> 0.008
Enter the percent annual decrease for U.S. population
Enter as a decimal.
For example, 0.5% is entered as 0.005
Enter the value >> 0.002

- Write a program in C# Write an application named DailyTemps that continuously prompts a user for a series of daily high temperatures until the user enters a sentinel value of 999. Valid temperatures range from -20 through 130 Fahrenheit. When the user enters a valid temperature, add it to a total; when the user enters an invalid temperature, display the error message:Valid temperatures range from -20 to 130. Please reenter temperature.Before the program ends, display the number of temperatures entered and the average temperature.arrow_forward. Write an application for a college’s admissions office.

- You are required to write a code that requests the user to enter three integer coefficients: a, b, and c in this order. Next, the user is requested to enter the equation degree: 1 for a linear equation and 2 for a quadratic equation. If the user enters an equation degree other than 1 or 2, the program must output Invalid. Based on the equation type, the program will process the coefficients and provide outputs as described below: First Scenario: Linear Equation When a linear equation is selected, the coefficient a is ignored and the equation format becomes: y=bx+c The program should check the slope of the line and accordingly print the values of the x-intercept, the y-intercept, and the line direction with respect to the x-axis each on a separate line. We have four possibilities: Slope is positive (i.e. b > 0): x-intercept = −cb, y-intercept = c, direction is UpwardSlope is negative (i.e. b < 0): x-intercept = −cb, y-intercept = c, direction is DownwardSlope is zero (i.e. b = 0)…arrow_forwardScenario:The owner of 'Cupcakes R Us' is in need of a web application to sell their bakery products via ecommerce.

The program validates all data entered the name can not be blank the state can only be the three states listed above. the bakery item must be a valid bakery item from the list above. the quantity can not <= 0 If the values are invalid, an error message is displayed to the user Otherwise: the values for the item and quantity are added to an array of items selected to be purchased.

Please take note of the following: 1. It must only request the user to enter a digit between 0 and 15, six times. It must be specified in the output display that it is "1st digit", "2nd digit", and so on up to "6th digit". 2. If the digit entered is more than 15, the application will notify the player by displaying the following message: "Error! Please only enter digits between 0 and 15! Repeat your choice!" And the program will be terminated. 3. If at least one digit from the Lottery draw matched (precise array position and digit), the output display must be, for example: "1 Match! Your bet is now available for the next draw!" 4. If no digit from the Lottery draw matched, the output display must be, for example: "No Exact Match Found; Please Retry!" 5. Note that repetition of input digit chosen by the player is allowed. 6. And finally, if all digit matches, it will give an output display, as an example: "Congratulations!"arrow_forward

The store manager wants an application that allows the salesclerk to enter the prices of two items. The half off should always be applied to the item that has the lowest price. The application should calculate and display the total amount the customer owes as well as the amount he or she saved. For example, if the two items cost $24.99 and $10.00, the half off is applied to the $10.00 item. The total owed is $29.99 and the savings is $5.00.
