Customized step counter Learning Objectives In this lab, you will Create a function to match the specifications Use floating-point value division Instructions A pedometer treats walking 2,000 steps as walking 1 mile. It assumes that one step is a bit over 18 inches (1 mile = 36630 inches, so the pedometers assume that one step should be 18.315 inches). Let's customize this calculation to account for the size of our stride. Write a program whose input is the number of steps and the length of the step in inches, and whose output is the miles walked. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value:.2f}') Ex: If the input is: 5345 18.315 the output is: You walked 5345 steps which are about 2.67 miles. Your program must define and call the following function. The function should return the number of miles walked.def steps_to_miles(user_steps, step_length) # Define your function here if __name__…

Module/Week 2 ASSIGNMENT (INPUT/OUTPUT)The number of permutations of a set of n items taken r at a time is given by the following formulan !⁄r !(n-r)!: where n! is the factorial of n, r! is the factorial of r, and (n-r)! is the factorial of the result of n-r. The factorial of a number n can be solved using the following formula: 〖n!=e〗^(-n) n^n√2πn. If there are 18 people in your class and you want to divide the class into programming teams of 3 members, you can compute the number of different teams that can be arranged using this formula (n !⁄r !(n-r)!). Write a C++ program that determines the number of potential team arrangements. You will need to use the double type for this computation. Use the Lab Template you set-up last week, proper formatting, and appropriate comments in your code. The output must be labeled clearly and formatted neatly.
