Problem definition: A college wants to know how well its students did on an exam. The following program summarizes the results. The program asks a user to enter the results pass (1) or fail (2) for 10 students. It displays the number of passed and the number of failed. It displays a message "Raise error" if the number of passes is more than 8 You are asked to identify statement with syntax errors by selecting them as wrong and the correct statements as right

Enter desired auto service: oil change You entered: Oil change (2) Output the price of the requested service. (4 pts) Ex: Enter desired auto service: oil change You entered: Oil change Cost of oil change: $35 The program should support the following services (all integers): • Oil change - $35 • Tire rotation--$19 Car wash - S7 If the user enters a service that is not listed above, then output the following error message Type here to search
Write a single scanf statement that reads user-entered time (three integers) and discards the user-entered characters between the numbers, in order, for hour (hh), minute (mm), and second (ss). For example, the user may enter the time as 12:23:21 or 12 23 21 or 12, 23, 21.

Question 18 Guessing Game Code a solution for the following problem. Post your program in the textbox below. (NOTE: Indenting matters.) • Hard-code an integer variable valid value from 1 to 10. Ask the user to guess your whole number and input that number. - Then compare the user's input to your literal number ani tell the user how they compare, is it greater than, less than or equal to each other.

Change Return Program: (Can you create flowchart for the following) The user enters a cost and then the amount of money given. The program will figure out the change and the number of twenty-dollar bills, ten-dollar bills, five-dollar bills, single-dollar bills, quarters, dimes, nickels, pennies needed for the change. You must have the maximum amount of higher denominations possible before allowing for lower denominations. For example, If your change is $18.88, You must have One Ten-dollar bill, One Five-dollar bill, Three singles, Three quarters, One dime and three pennies. There should be no nickels; No three Five-dollar bills etc.
1. The program accepts n number of quiz scores (User enters the quiz scores until -1) 2. After accepting quiz scores, the program will accept the grades for Midterm exam, Final exam, and Final project. 3. The program computes the Final grade: Ave of Quizzes 40%, ME 20%, FE 20%, FP 20% 4. The program displays the Final grade and grade equivalent (A, A, B, etc.) based on the attached photo
Assume that grade is a variable whose value is a letter student_grade-- any one of the following letters: 'A', 'B', 'C', 'D', 'F". Assume further that there are the following int variables, declared and already initialized: acount, bcount, ccount, dcount, fcount. Write a switch statement that increments the appropriate variable (acount, bcount, ccount, etc.) depending on the value of grade. So if grade is 'A' then acount is incremented; if grade is'B' then bcount is incremented, and so on.

Chapter 5. PC #2. Retail Price Calculator (page 312) Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example: • If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00. • If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50. The program should have a method named calculateRetail that receives the wholesale cost and the markup percentage as arguments, and returns the retail price of the item.
