.Prime NumbersIn this task, you will implement a program that takes as input a number n and produces alist of integers less than or equal to n that are prime. The way to think about a problem isto break it down into individual parts. Start by creating a function isPrime() that checkswhether it’s argument is prime or not. The pseudocode for checking isPrime is givenbelow, there are better ways to do it… this is just one.6Step 1: count = 2Step 2: while count < numberStep 3: if count divides the number evenly return falseStep 4: add 1 to countStep 5: Goto step 2Step 6: return true
USING C++
A pedometer treats walking 1 step as walking 2.5 feet. Define a function named FeetToSteps that takes a double as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. Then, write a main program that reads the number of feet walked as an input, calls the function FeetToSteps() with the input as an argument, and outputs the number of steps.
Use floating-point arithmetic to perform the conversion.
Ex: If the input is:
150.5
the output is:
60
The program must define and call a function:int FeetToSteps (double userFeet)
In Python: can you this problem be solved without using "while" and "for".
Write a function called is_prime that receives a single integer value between 1 and 50 determines whether or not the integer is a prime. To determine if a number less than 50 is prime, you only need to divide it by all prime numbers less than or equal to the square root of 50 (i.e., 2, 3, 5, and 7). If any of them are smaller than the number and evenly divide the number, then it is not prime. By definition, 1 is not prime. Your solution should use the guess-and-check pattern.
Write a main() function in your file to exercise your function to show that it works correctly. Your test implementation should not rely on visual inspection to determine if the tests pass.

- A company wants to transmit data over the telephone but is concerned that its phones may b tapped. It has asked you to write a program that will encrypt the data so that it may be transmitted more securely. All the data transmitted is 4 digit integers. Your program should read a four digit integer entered by the user and calls a function encrypt which takes four digits as arguments and encrypt it as follows . Replace each digit with the result of adding 4 to the digit and getting the remainder after dividing the new value by 10. . Calls another function swap which swaps the first digit with the third, and second digit with the fourth using pass by reference. Then it prints the encrypted integer.arrow_forwardA pedometer treats walking 1 step as walking 2.5 feet.

- Python Programming- Computer-Assisted Instruction Part 1: Computer-Assisted Instruction (CAI) refers to the use of computers in education. Write a script to help an elementary school student learn multiplication. Create a function that randomly generates and returns a tuple of two positive one-digit integers. Use that function's result in your script to prompt the user with a question, such as: How much is 6 times 7? For a correct answer, display the message "Very good!" and ask another multiplication question. For an incorrect answer, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. Part 2: Varying the computer's responses can help hold the student's attention. Modify the program so that various comments are displayed for each answer. Possible responses to a correct answer should include 'Very good!' , 'Nice work!' and 'Keep up the good work!'

Your program should be able to add,subtract, multiply, and divide two fractions. Write a separate function for addition,subtraction, multiplication and division.

- please code in python Here's an example created by rotating a square 9 times: Write a Python program that will produce our simplified "spirograph" images from squares. Your program should include a function: spiro(num, side) that takes two arguments: the number of squares to draw in one revolution, and the side length of each square in the figure. Remember: there are 360 degrees in a circle. Here is a function that demonstrates how to draw a randomly colored filled square. You’ll want to copy-paste this function into your program, and call this function from within a loop in your spirograph function, so that it draws multiple squares: import turtle, random turtle.speed(0) turtle.delay(0) def filled_square(side): r = random.random() g = random.random() b = random.random() turtle.color(r,g,b) turtle.begin_fill() for i in range(4): turtle.forward(side) turtle.left(90) turtle.end_fill()arrow_forwardModify the program so that it does the following: Performs a function that gets the area of a rectangle. The function must receive two parameters (decimal numbers) that represent the base and height of the rectangle and must return the calculated value (decimal number). Perform a second function that obtains the total area of a rectangular prism with a rectangular base. The total area of such a prism is equal to the sum of the areas of each of its faces. It uses calls to the previous function for this calculation. Call this last function in the main with user data. Execution example Give me the base: 21.3 Give me the height: 10 Give me the depth: 2.0 The total area of the prism is: 551.2arrow_forwardThe ceiling of a floating-point number x is the smallest integer that is still larger than or equal to x. Alternatively, the ceiling of a floating-point number x is what you get when you round x up to the nearest integer. For example, the ceiling of 2.1 is 3, the ceiling of 0.9 is 1, the ceiling of -4.5 is -4, etc. Write a function called ceiling() to compute the ceiling of a float input parameter that returns one integer value. You may not use python’s ceil() or floor() functions. Your function may use int()/float() functions, and the floor division operator (i.e., '//').arrow_forward
