# Introduction In this lab, you are required to create a program that calculates the standard deviation of an array of numbers by implementing the `calculateSD()` function, which finds the sum, mean, difference, square, and variance, and returns the square root as the standard deviation, and the `main()` function that takes user input for an array, calls the `calculateSD()` function, and prints the result up to three decimal places.
