This isn't difficult, but ... it smells of homework so I'll give you no code!

All you need to do is:
1) Create two variables: minLength (defaulted to int.MaxValue) and minIndex (defaulted to -1)
2) use a for loop to look at all elements in your array with a index variable that runs from 0 to the length minus 1.
2.1) If the current value at the index is shorter than minLength set that as the new minLength, and set minIndex to the current index.
3) After the loop, minLength says how short the shortest was, and minIndex says where it was.

Simple, no?

Solution 2

If you are familiar with Linq, you could do this with one line of code.

C#

string[] test = { "absc", "abc", "abcder", "abcdg" };
var smallest = Array.IndexOf(test, test.First(s => s.Length == test.Min(st => st.Length)));

If they can't work out how to traverse an array with a for loop something tells me they won't understand link :-)
