C++ How to Program (Early Objects Version)
- [Calculate grades’ average for a student] write a program that calculates the student grades’ average for a semester for the number of courses taken in that semester. Your program should do the following: 1.Read from user the number of courses (n) 2. Then, read the courses’ grades for n times (Hint: use a loop) 3.If a grade is grater than 100 or less than 0, ask the user to enter the grade again. 4.Calculate the average of grades using the following formula: average = (sum of grades) / n 5.Print out the average grade on the screen. Note: Always use appropriate data types.arrow_forwardHi! I need help with this homework! (it is C prgramming ) Thank youarrow_forwardC# (Guess the Number Game) Write a program that plays “guess the number” as follows: Your program chooses the number to be guessed by selecting an int at random in the range 1–1000. The program then displays the following text in a label: A TextBox should be used to input the guess. As each guess is input, the background color should change to red or blue. Red indicates that the user is getting “warmer,” blue that the user is getting “colder.” A Label should display either “Too High” or “Too Low,” to help the user zero in on the correct answer. When the user guesses the correct answer, display “Correct!” in a message box, change the Form’s background color to green and disable the TextBox. Recall that a TextBox (like other controls) can be disabled by setting the control’s Enabled property to false. Provide a Button that allows the user to play the game again. When the Button is clicked, generate a new random number, change the background to the default color and enable the TextBox.arrow_forward
- Parking Charges) A parking garage charges a $2.00 minimum fee to park for up to threehours and an additional $0.50 per hour for each hour or part thereof over three hours. The maximumcharge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hoursat a time. Write a program that will calculate and print the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for eachcustomer. Your program should print the results in a tabular format, and should calculate and printthe total of yesterday's receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format:Car Hours Charge1 1.5 2.002 4.0 2.503 24.0 10.00TOTAL 29.5 14.50arrow_forward) that generates a random even positive integer less than 10 Write a program (Li and displays, using asteriskS, a filled diamond.

(Geometry: area of a pentagon) The area of a pentagon can be computed using the following formula (s is the length of a side): Area 5x s² 4 X tan TT 5 Write a program that prompts the user to enter the side of a pentagon and displays the area. Here is a sample run: Enter the side: 5.5 Enter The area of the pentagon is 53.04444136781625arrow_forward
- (IN C LANGUAGE) Cumulative Addition: Computer selects a number between 7 and 23 at random. User will only add 2, 3 or 5 numbers to reach that number. For example: To reach 14:User will enter 5 5 2 2 (4 input).Also he can enter 2 2 2 2 2 2 2 (7 input) or 3 3 3 3 2 (5 input)arrow_forward) /₹3soos alspaarrow_forward(Financial: credit card number validation) Credit card numbers follow certain pat- terns. A credit card number must have between 13 and 16 digits. It must start with: 4 for Visa cards 5 for Master cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustra- tion, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 4388576018402626 → 2 * 2 = 4 → 2 * 2 = 4 → 4 * 2 = 8 → 1 * 2 = 2 6 * 2 = 12 (1+ 2 = 3) → 5 * 2 = 10 (1+ 0 = 1) → 8 * 2 = 16 (1 + 6 = 7) → 4 * 2 = 8arrow_forward
- (Python) Please write a program that creates steps. You are expected to take in a single positive integer which will be used as the number of steps in your staircase. The program only accepts integers greater than 0 and less than 500. If 0 is entered a message stating "Your staircase has no steps." and if the user enters a value greater than or equal to 500, a message stating "I can't build a staircase that tall." For all other values not within the valid range or not integers an "Invalid staircase size provided." will be displayed to the user. The program will always run only once for each user input. One thing to note, the messages should be the return string from your printSteps() function and printed from the calling function. Additional Requirements: The very first step in the staircase will be left-aligned and for each subsequent level, the step will move above and to the right of the prior step. There are no spaces after the right of any of the steps. The bottom-most row ends…arrow_forwardQ1. FizzBuzz problem:- Write a program which return "fizz" if the number is a multiplier of 3, return "buzz" if its multiplier of 5 and return "fizzbuzz" if the number is divisible by both 3 and 5. If the number is not divisible by either 3 or 5 then it should just return the number itself? .arrow_forwardQ7-Write a program that simulates a simple calculator. It reads two integers and a character. If the character is a +, the sum is printed; if it is a -, the difference is printed; if it is a *, the product is printed; if it is a /, the quotient is printed; and if it is a %, the remainder is printed.
