Array question ??

How do I total all the values in an array?

and average them?

Code:

const int MAX = whatever;
int array[MAX];
int sum = 0;
for(int i = 0; i < MAX; ++i)
{
	sum += array[i];
}
double avg = sum / MAX;

Wow, that's even simpler than I thought.

actually you may want to declare sum as a double, or typecast one of the ints in the division.

Code:

double sum = 0;
//...

or

Code:

double avg = double(sum) / MAX;

otherwise, you will get an int placed into a double, and the int will be output.

You're absolutely right, Alpha. I just coded that out in like 30 seconds, so I overlooked that.
