- (Factorials) Factorials are used frequently in probability problems. The factorial of a positive integer n (written n! and pronounced “n factorial”) is equal to the product of the positive integers from 1 to n. Write an application that calculates the factorials of 1 through 20. Use type long . Display the results in tabular format. What difficulty might prevent you from calculating the factorial of 100?arrow_forward(Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forwardQ3. (Dice Rolling) Write a program that simulates the rolling of two dice. The program should use rand to roll the first die and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36 possible combinations of the two dice. Your program should roll the two dice 10,000 times. Use a one-dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable (i.e., there are six ways to roll a 7, so approximately one-sixth of all the rolls should be 7). 1 2 3 4 5 1 2 4 6 7 3 4 6 7 3 4 5 7 8 9 4 7 8 9 10 7 8 10 11 7 10 11 12 Row\Col 3.arrow_forward
- (Airline Reservations System) A small airline has just purchased a computer for its new automated reservations system. The president has asked you to program the new system. You’ll write a program to assign seats on each flight of the airline’s only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1– 5). If the person types 2, then your program should assign a seat in the economy section (seats 6– 10). Your program should then print a boarding pass indicating the person's seat number and whether it’s in the first class or economy section of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding element of the array to 1 to indicate that the seat is no longer available. Your program should, of course,…arrow_forward(Financial application: compare loans with various interest rates) Write a program that lets the user enter the loan amount and loan period in number of years and displays the monthly and total payments for each interest rate starting from 5% to 8%, with an increment of 1/8.arrow_forward(Hard drive storage capacity) If you buy a 40 GB hard drive, then chances are that the actual storage on the hard drive is not 40 GB. This is due to the fact that, typically, a manufacturer uses 1,000 bytes as the value of 1K bytes, 1,000 K bytes as the value of 1 MB, 1,000 MB as the value of 1 GB. Therefore, a 40 GB hard drive contains 40,000,000,000 bytes. However, in computer memory,1 KB is equal to 1,024 bytes, and so on. So the actual storage on a 40 GB hard drive is approximately 37.25 GB. (You might like to read the fine print next time you buy a hard drive.) Write a program that prompts the user to enter the size of the hard drive specified by the manufacturer, on the hard drive box, and outputs the actual storage capacity of the hard drive.arrow_forward
- (Financial application: loan amortization schedule) The monthly payment for a given loan pays the principal and the interest. The monthly interest is computed by multiplying the monthly interest rate and the balance (the remaining principal). The principal paid for the month is therefore the monthly payment minus the monthly interest. Write a program that lets the user enter the loan amount, number of years, and interest rate, and then displays the amortization schedule for the loan.arrow_forward( MindTap - Cenage )Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num). If diff is greater than or equal to 15 and less than 30, the…arrow_forward((PYTHON)) Q1- Ask the user to write a number 8 times. Find the sum and the average of all those numbers then display for the user the answer of both the sum and the average. Q2- Ask the user to guess what your favorite color is. If he does not answer correctly, ask him if he wants to try again. If he does not want to try again, display for him the correct answer.arrow_forward
- (Cost of driving) Write a program that prompts the user to enter the distance to drive, the fuel efficiency of the car in miles per gallon, and the price per gallon, and dis- plays the cost of the trip.arrow_forward(HTML & Javascript) Create a nested loop program that generates a multiplication table, but instead of a standard 10 by 10 table, the software allows the user to key in two numbers (the beginning and ending values), and then a multiplication table appears below it after pressing the button. When the user enters values that are out of range (between the values 2 and 10), the software will display a warning box that says "Please enter numbers between the values 2 and 10," and the computer will not create the desired result unless the user corrects the values. An example is shown belowarrow_forward(PYTHON) A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 3.9 Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4 The nutritionist asks you to write a program on *PYTHON* that will make these calculations.arrow_forward
