A text file of ordered pairs are to be inputted into the .cpp file using cin. (The txt file is not embedded in the program, it is called from the terminal when it is run). Once it has been imported, write two methods: minDistance() and maxDistance(). minDistance finds the two ordered pairs that are closest together. maxDistance finds the two ordered pairs that are farthest from each other.

The distance formula is as follows:

sqrt((x1 - x2)^2 + (y1 - y2)^2).
