Write a function that receives an array of float numbers and its and then it computes and returns the sum of the array elements. The function prototype is: float arraySun(float x[], int size); b) Write a function that receives two arrays of float numbers and their size, and then it uses the arraySum() function to compute the deviations from the mean for the first array and stores them in the second array. The function prototype is: void get Deviations(float x[], float deviations[], int size); c) Write a C++ program in which you do the following: 1. Initialize a static arrays p[] with the data in the following table: 2. Create a dynamic float array called pdeviations which has the same number of elements as the array p. 3. Using the getDeviations() function, store the deviations of p in the array pdeviations. 4. Display the values of array p and its deviations side by side and properly labeled, as in: 5. Also display the sum of pdeviations. 6. Add your source file and output screen to the word document.
