In C++ please

Write a function that takes an integen n and returns the sum (double data-type) of the squanes of the first positive integers. For example, sum-of_squanes (3} should return 12+22+32 =14. Write a C++ program contains function called array_min, that takes array of integers and integer size as parameters, then the function will calculate and print the minimum value in the array without returning value. Write a ct+ program that reads in a list of integens from the user, until the user enters the value 1. The program should then print out the sum of even numbers in the 11st
