You first write down the definition. Then from the definition, translate it into code.

Kindly show us your attempt first. This way you can learn more about things and improve. If you are stuck or have a doubt, feel free to ask about it here.
The problem require you to simply iterate over the array to find the maximum and minimum element respectively. The range is defined by [min,max], where [ and ] signify inclusion. Also, during the iteration, keep adding values of every element to a variable sum to get the average (average=sum/size).
These problems can also be solved using standard library functions. Assuming that your data is in an array a[] of size n:
0) For finding the maximum and minimum element of a range/container:
auto data = std::minmax_element(a,a+n);
The variable data is a pair, where the first element is the minimum value and the second is the maximum value.
1) For finding average of the range of elements:
double average = (std::accumulate(a,a+n,0)/static_cast<double>(n));
Accumulate calculates the sum of the elements in the range. This is then used to get the average.
