57,712 PointsHi Luis,
You have an array called temps which you want to iterate over using a for loop.
You've created a new variable of type float for the iteration. That's not what you want. Your array is full of NSNumber objects, so use a new NSNumber. As this is a new variable you'll need the pointer marker too. I called my variable x because that's easy and local to the loop only.
Inside the loop you want to add up the contents of your array, which is called temps not tempsArray. Store that cumulative value in runningTotal. As runningTotal is a float you need to cast the value of x before you can add it to the variable. The question explains how to do that. with my variable called x it look like [x floatValue].
After the loop has ended, divide runningTotal by the length of the array (use the [count] attribute). Store the result of that in the variable average you created in task 1.
Let me know how you get on - post your code and we'll work through it.
Steve.
