Write an application in Visual Studio with C# that handles a student report card. The application shall save the marks of computer science, math and English. Each subject has a total of 50 marks. If a student obtains at least 75/150 marks, an event will trigger and show a congratulation message on passing the exam. Otherwise, it will display an “F” grade.
Write a C# program named InchesToCentimeters that declares a named constant that holds the number of centimeters in an inch: 2.54. Also declare a variable to represent a measurement in inches, and assign a value.
Display the measurement in both inches and centimeters—for example, if inches is set to 3, the output should be: 3 inches is 7.62 centimeters.
Note: For final submission, set the number of inches equal to 3.
Write a program that declares a constant named QUARTS_IN_GALLON which holds the number of quarts in a gallon (4). Also declare a variable named quartsNeeded to represent the number of quarts needed for a painting job, and assign an appropriate value. Compute and display the number of gallons and quarts needed for the job. Display explanatory text with the values—for example, A job that needs 18 quarts requires 4 gallons plus 2 quarts.
When submitting the program for testing/grading, assign the value 18 to quartsNeeded.

- Write a program named Eggs that declares four variables to hold the number of eggs produced in a month by each of four chickens, and assign a value to each variable. Sum the eggs, then display the total in dozens and eggs. For example, a total of 127 eggs is 10 dozen and 7 eggs.arrow_forwardWrite a C# program named Inches ToCentimeters that declares a named constant that holds the number of centimeters in an inch: 2.54. Also declare a variable to represent a measurement in inches, and assign a value.

Note: For final submission, set the number of inches equal to 3.arrow_forwardthis is a mindtap C# Exercise The Saffir-Simpson Hurricane Scale classifies hurricanes into five categories numbered 1 through 5. Write an application named Hurricane that outputs a hurricane’s category based on the user’s input of the wind speed. Category 5 hurricanes have sustained winds of at least 157 miles per hour. The minimum sustained wind speeds for categories 4 through 1 are 130, 111, 96, and 74 miles per hour, respectively. Any storm with winds of less than 74 miles per hour is not a hurricane. If a storm falls into one of the hurricane categories, output This is a category # hurricane, with # replaced by the category number. If a storm is not a hurricane, output This is not a hurricane.

- The temperature of an object changes when it absorbs or loses thermal energy. It is possible to relate the amount of heat transferred, denoted by a variable q with units of joules, to the quantity of the substance m, by the following equation: q = mCsΔt Write a script that calculates amount of heat transferred for any amount of aluminum. Aluminum has a specific heat Cs = 0.897. The program should prompt the user to enter values for Δt and m, and should return the amount of heat transferred in units of joules. Test the program with values of 20 ℃ and 100 g.arrow_forward1# Write a program that allows users to choose from one of three shapes: Squares, Circles or (right) Triangles. Allow the user to use the first letter of the shape (S, C, T) to specify what they want. After the shape is selected, ask the user for the appropriate data to calculate the shape's area, and then and print that area value to the screen for them. Area formulas you can use: Triangle: % base x height Square: length x length Circle: % Pl x radius? Notes: The floating-point data type will be your friend here. Round your area answer so that no more than 2 decimal places are shown when printing on the screen. You can use 3.1415 for Pl; Think about this as a CONSTANT in your code. For this part and especially part (b) below, think about componentizing your code. So one gigantic main() is not a best practice and not what we want to see here. Remember what we discussed about "procedural decomposition" and functions last week!arrow_forwardCreate a program is C# called MarshallsRevenue.The programs prompt a user for the number of interior and exterior murals scheduled to be painted during the next month by Marshall’s Murals. Next, the programs compute the expected revenue for each type of mural when interior murals cost $500 each and exterior murals cost $750 each. The applications also display the total expected revenue and a statement that indicates whether more interior murals are scheduled than exterior ones. Now, modify one or both of the applications to accept a numeric value for the month being scheduled and to modify the pricing as follows: • Because of uncertain weather conditions, exterior murals cannot be painted in December through February, so change the number of exterior murals to 0 for those months. • Marshall prefers to paint exterior murals in April, May, September, and October. To encourage business, he charges only $699 for an exterior mural during those months. Murals in other…arrow_forward
- C# Write a GUI program named InchesToCentimetersGUI that allows the user to input a measurement in inches, click a Button, and output the value in centimeters. There are 2.54 centimeters in an inch. Display the output in both inches and centimeters – for example, if inches is set to 3 by the end user, the output (shown after clicking the button) should be: 3 inches is 7.62 centimeters.arrow_forwardUsing C# in Microsoft Visual Studio create an application that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you can use Button controls, or clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4. A winner is selected according to the following rules:• If one player chooses rock and the other player chooses scissors, then rock wins. (Rock smashes scissors.)• If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors…arrow_forwardA code in c++ or python A program that asks you to enter the name of a movie or series, and then proceed to ask how much you rate the movie or series on a scale of 1 to 10, then ask what rating you would give the series or movie, and have options for example: G, PG, PG-13, R and finally, a thank you message for your comments appears.arrow_forward
- Write a program that calculates and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:BMI = weight × 703 / height2where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person’s weight is considered to be optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered to be underweight. If the BMI value is greater than 25, the person is considered to be overweight please write code on c++arrow_forwardWrite a program that declares a named constant to hold the number of quarts in a gallon (4). Also declare a variable to represent the number of quarts needed for a painting job, and assign an appropriate value—for example, 18. Compute and display the number of gallons and quarts needed for the job. Display explanatory text with the values—for example, A job that needs 18 quarts requires 4 gallons plus 2 quarts. Save the program as QuartsToGallons.java. Convert the QuartsToGallons program to an interactive application. Instead of assigning a value to the number of quarts, accept the value from the user as input. Save the revised program as QuartsToGallonsInteractive.java.arrow_forwardHere is my assignment that must be in C#: Write an application named EnterUppercaseLetters that asks the user to type an uppercase letter from the keyboard. If the character entered is an uppercase letter, display: OK; if it is not an uppercase letter, display the error message: Sorry - that was not an uppercase letter. . The program continues until the user types an exclamation point (!). An example of the program is shown below:arrow_forward
