C++

Write a program that a) Inputs a positive integer n from the keyboard where nc=50. If n is out of range then print out an error message and ask for another input. This process repeats until a valid value for n is obtained b) Inputs two 10 arrays of doubles A and B (of size n) from the keyboard. c) Inputs an integer k (1-3) from the keyboard d) fk = 1 then it calculates the average value of All and prints it to the screen a) ifk - 2 then it calculates the maximum value of B and prints it to the screen 1) ifk = 3 then it reverses the elements of A and prints A to the screen (Do not introduce another array or use any library functions) For example if A-12 75 25 10 results in A- [10 25 572)
