I've written a program that reads two values. I then want it to repeatedly read a further two values until someone enters 0.
The reason why I want to do this is so I can use it to work out some calculations and ratios. So effectively at every calculation except the first, I would be printing out the results and the ratio of the newly computed data to the previously computed data.
But I'm really confused on how I would go about this, such as how variables update in the loop to be compared to the previous etc
