Modify the program below so that it computes and prints out

the standard deviation of a given data array.

The program allows the user to input the number of elements

(n) in the array "data", then it asks the user to keyin the

data array elements. The main function calls the getSTD

function to compute STD and return its value.

The program contains some logical errors that prevents it

from producing the correct output.

Identify and fixt hese errors, so that the program can produce

the sample runs below:

Sample Run 1:

How many elements ? 7

Enter 7 elements: 8 7 6 5 4 5 4 5

8:7:6:5:4:5:4:

Standard Deviation = 1.82401

Sample Run 2:

How many elements ? 10

Enter 10 elements: 8 7 6 5 4 9 8 7 6 7

8:7:6:5:4:9:8:7:6:7:

Standard Deviation = 1.41774
