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__…

AIM- Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. PROBLEM STATEMENT- The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the 'D' register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register 'D'. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78,…

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. Submit C++ Programming Assignment 2 by 11:59 p.m. (ET) on Monday of Module/Week 2.
Use c program only please
describe how you would create the program and why referencing which data structure you would use. c++ Write a program that reads a set of floating-point numbers and prints out the ten largest numbers. As you process the inputs, do not store more than eleven numbers. When it holds more than ten values, remove the smallest value, as it cannot be a part of the answer.
Exercise 6 Write a program to perform the following arithmetic operation; addition, subtraction, multiplication, and division. The user are required to enter 2 integers as the input. By using these inputs, the user can select which arithmetic operation to be done. The user can perform the operation on one time inserted data as many times as they wish. In this exercise, you need to fully utilize the use of pointers and funetions.
