Problem

Write a C$++$ program that reads a text file containing integers $($one per line$)$ and calculates:

The Mean.

The Standard Deviation $($Population$).$

The Median.

Required functions

read$\_$file : this function will receives a file path $($thr txt file$),$ and an array of double. This function will read the information from the txt file and store it into the given array.

Note: You need to identify if the array needs to be pass by value or reference.

mean : this function receives an array of double and compute the mean of the given numbers. $($statistical mean$).$

median : this function receives an array of double and the length of the

loops and files

array as integer. This function compute median of a given set of numbers.

Note: You need to consider if the size of the array is even of odd to implement the right formula to compute the median.

std$\_$deviation : this function receives an array of double, This function compute standard deviation of a given set of numbers. Note: the standard deviation is compute based on population.

Example Input $($numbers$.$txt$)$:

Expected output

Mean Value: $4\mathrm{.}8$

Median Value: $5$

standard Deviation: $2\mathrm{.}54$
