Normally you index using c[0] or c[1], etc. Negative indexing lets you go from last to first. Just use negative numbers. c[-1] c[-2] etc.
To extract the fourth item from a list with four items, it would be c[-1].

Sher Agha Hewadmal normally you would simply use positive indexing to find the nth element from the left. The positive index would be n - 1. In this case n is 4, so that would be 4 - 1 = 3.
It is easy to convert a positive index into a negative index. Subtract the length of the array from the positive index. In this case the array has 4 elements, so that would be 3 - 4 = -1.
Here is a program I wrote where you can try it out:
