Math C++

  Write a C++ program that creates the following functions:

 double Max (double Values[], int size);

 double Min (double Values[], int size);

 double calc Average(double Values[], int size);

 double calc Median(double Values[], int size);

double calc Standard Deviation (double Values[], int size);

 Write a driver program that creates an array with 11 values and calculates all of the preceding values. Display the values to the user. Create a second array that has 10 values and display all of the preceding values.

Note: You do not need to get input from the user. Must use the previous functions prototype.

C++ Pay problem

/////////////////////////////////////////////////////////////////////////////////////////////////////
// Program Description:Write a program that calculates the daily      //
////pay and total pay of a person who works for a penny the first       //
//day and their pay doubles every day after that. The program must //
