Simple array issue

[NRich5]

having trouble getting this to work correctly. the question is write a function called calcMean that accepts an array of doubles named data and returns the simple average (mean) of the data elements.

this is what I have so far.

  #include <iostream>



double calcMean(double A[], int arraySize)

{
	double data = 0;
	for (int i =0; i < arraySize; i++)
		data += A[i];
	double mean = data/arraySize;

	return mean;
}

try starting a new project with a different name and put your whole code in here.

You need to have a main() function so the computer knows where to start your program.
