Question

C++

I need help with this part of the code. It is part of a broader program that will include this code.This time you are going to create a speedometer calculator. In this program you will ask the user for the tire sizes (old & new). Then you will calculate the difference between the actual speed of the vehicle and what the speedometer shows in 10 mph increments from 10-100. You will save all of actual speeds in an array. For example and using the ratio difference below, at 60 mph on the speedometer the actual speed of the vehicle is 66 mph. so you will store the actual speed in the array of 66 mph. For the display, see the picture below. Oh yeah, don’t forget about giving the user the ability to run the program as many times as they want, again like in the picture below. Since this is a ratio problem we will be dealing with it in that manner. What that means is that if we have a tire diameter that is 30” (inches) and we increase the size to 33” we have a 10% increase in size therefore our speedometer will also be off by that same 10%. Formula: tireRatio = newTireSize / oldTireSize

Answer 1

Note: Could you plz go this code and let me know if u need any changes in this.Thank You

return 0;
