Complete the program minmax.cpp which uses two functions readdata$()$ and minmax$()$ to find the minimum and maximum of a set of floats stored in the file minmaxin.txt$.$

The main program opens the input and output files, and allocates a float array $x,$ then calls the functions readdata $()$ and minmax $()$ and finally prints the minimum and maximum values to the output file minmaxout.txt$.$

The input file minmaxin.txt includes a single column of data, where the first number $($an int$)$ indicates the number of floats which follow. You can assume that the file holds no more than $100$ values.

The function readdata$()$ reads the first number, $n,$ from the input file and then reads the following $n$ floats into the array.

The function minmax $()$ computes the minimum and maximum values found in the array.

Here is the expected program output:

The array has $80$ elements

The maximum value in the array is $63\mathrm{.}606$

The minimum value in the array is $4\mathrm{.}8089$
