1. Write a program. After reading the specifications below, write the pseudo code in the comments before writing the code. The program should ask the user to enter an item's wholesale cost and it markup percentage. (cost of product * markup percent = markup) (retail = cost of product + markup) The program should validate the inputs. (Note: markup should be greater than zero but less than one) The program should display the item's retail price with two decimal places. The program should have a void function named calculateRetail that receives the wholesale cost and the markup percentage as arguments, does the math and displays the retail price. The program should employ a do-while loop to ask the user if they desire to find the retail price of another product.
2. Write a program. After reading the specifications below, write the pseudo code in the comments before writing the code. The program should ask the user what would they like to do: convert a Fahrenheit temperature to Celsius (F = 9/5 C + 32) or convert a Celsius temperature to Fahrenheit. (C = 5/9(F-32)) The program should validate the input and then, depending on the choice the user makes, ask for a temperature and do the conversion. Use a switch case to handle the choice the user makes. Each choice should call a void function to do the math and display the result to one decimal place. Be sure to test your program.
3. Write a program. After reading the specifications below, write the pseudo code in the comments before writing the code. The program should ask user for the mass and velocity of an object. Validate inputs. Pass inputs to a void function that calculates the kinetic energy of the object. formula is KE = 1/mv2 void function should calculate and display results. Program asks if user wants to calculate the KE of another object and starts over if Yes.
