- Design the logic for a program that calculates the projected cost of a renovation project. Assume that the labor cost is $50 per hour. Design a program that prompts the user for a number hours projected for the job and the wholesale cost of materials. The program computes and displays the cost of the job, which is the number of hours times the hourly rate plus the 120% of the wholesale cost of materials. The program accepts data continuously until 0 is entered for the number of hours. Use appropriate modules, including one that displays End of programwhen the program is finished. Upload your finished flowchart for grading.arrow_forwardDesign the logic (flowchart and pseudocode) using arrays for a program. It allows a user to enter 10 numbers, then displays all of the numbers in reverse order, the largest number, and the smallest number.arrow_forwardExplain how to check for an invalid input number and prevent it being used in a program. You may assume that the user enters a number.arrow_forward
- Write algorithms using pseudocode and draw the flowcharts for the following problems. a) Calculate the total of a retail sale. Ask the user for the following: The retail price of the item purchased the sales tax rate Once these items have been entered, the program should calculate and display the following: The sales tax for the purchase The total of the bill Example: If the sales tax rate is 7%, compute 7% of the purchase, add it to the total purchase that would be total of bill. Total of bill = purchase + 7% of purchasearrow_forwardA and BonlyIn this program, you are asked to write a program in assembly which works as a simple calculator.The program will get two integer numbers, and based on the requested operation, the result shouldbe shown to the user.a. The program should print a meaningful phrase for each input, and the result.i. “Enter the first number”ii. “Enter the second number”iii. “Enter the operation type”iv. “The result is”b. The user should enter 0, 1, and 2 to tell the program the types of operation add, sub, andmultiply, respectively.c. How many registers do you need to implement this program?d. What system calls do you need to write this program?arrow_forwardThe programmer intended the following pseudocode to display the numbers 1 through 60, and then display the message “Time’s up!” It will not function as intended, however. Find the error. Declare Integer counter = 1 Const Integer TIME_LIMIT = 60 While counter < TIME_LIMIT Display counter Set counter = counter + 1 End While Display “Time’s up!”arrow_forward
