Im stuck on a Software Development question and need an explanation.
The standard deviation is defined to be the square root of the average of the four values. Use two functions. One function to calculate the average, this function should be with Return Type double. Second Function should be to calculate standard deviation, this function should be with Return Type void. Allow the program to continue until the user tells the program he/she is finished.
average = (s1 + s2 + s3 + s4) / 4
The standard deviation is computed as
standard_deviation = sqrt( ( (s1 -average)2 + (s2 average)2 + ( s3 average)2 + (s4 average)2 )/4 ).
SAMPLE OUTPUT
Enter four decimal numbers =>12.3 13.4 10.5 9.0The average = 11.3The standard deviation of these numbers = 1.68375Please enter y to continue =>y
Enter four decimal numbers =>1 2 3 4The average = 2.5The standard deviation of these numbers = 1.11803Please enter y to continue =>n
file type : cpp
Point Distribution:
-50 Does not compile
-5 Warnings
-5 No description multiple line comments (name, date, etc)
-5 No single line comments (logic, input, output, etc)
-10 Incorrect Standard Deviation
-10 Incorrect Average
-10 Does not use at least 2 programmer defined functions
-10 Does not match the Return Type constraints
-10 Does not continue calculations as long as user wishes
