Question
In C language / Please don't use (sprint) function. Write a function fact_calc that takes a string output argument and an integer input argument n and returns a string showing the calculation of n!. For example, if the value supplied for n were 6, the string returned would be 6! 5 6 3 5 3 4 3 3 3 2 3 1 5 720 Write a program that repeatedly prompts the user for an integer between 0 and 9, calls fact_calc and outputs the resulting string. If the user inputs an invalid value, the program should display an error message and re-prompt for valid input. Input of the sentinel -1 should cause the input loop to exit.
Note: Don't print factorial of -1, or any number that is not between 0 and 9.

- Write a python application to simulate an Online Book Shop. Notes: Option 1 and Option 2 must display the list of books to the user. The Main function accounts for invalid options. Program displays error message for invalid user option, invalid ISBN number or any invalid title.The programmer can create the book title, price, and ISBN information for the books. Each item consists only one string of comma-separated data: book ISBN number, title, and price. A customer can purchase some books either by ISBN number and/or by title. If the user input an invalid number or book title, the program should display an error message. The user can stop shopping with “checkout” option , which triggers the checkout() function that computes the total cost of the books in the cart. A customer will be provided the following menu option while shopping at the book shop: Option 1. Purchase by ISBN: User can purchase a book by its ISBN number.

A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.arrow_forward
- ***in python only*** use turtle function Define the concentricCircles function such that: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the largest (i.e., outermost) circle, and then every other circle out to the edge alternates between that color and the 'other' color. The difference between the radii of subsequent circles is always the same, and this difference is also equal to the radius of the smallest circle. Put another way: the distance between the inside and outside of each ring is the same.

The program should display the value that is the greater of the two.arrow_forward
- in C++arrow_forwardin pythonarrow_forwardScenario: I am trying to create a recursion function that takes a number from the user. That number then goes through to equations where it squares the number and takes the square root of it. Then, that value is supposed to be sent back through the function, through the same equations. Then, I am trying to output the value of each iteration. The amount of iterations is a random number. This code is in C++ and I am using Visual Studio 2023. I have attached the code I, myself, typed and picture of the output. Also, this is a header file that is being called from my source.cpp file (case 5 in switch case). That is why I am entering 5 as the first input when I run the program. Problem: The output only shows one iteration of calculation, then goes straight back into taking an input from the user. What am I doing wrong?arrow_forward
