Write a C++ function that receives an integer array and returns the standard deviation of the values in the array. Assume, an array of size N. The Standard Deviation is defined as following where xi indicates array elements and (x bar) indicates average value of xi's. Sample Standard Deviation: s-VN-EO: F) Write a C++ function that receives an integer array and returns the standard deviation of the values in the array. Assume, an array of size N.
