The First Step

The first step in is to check that the error is reproducible. Computers are deterministic, which means that they will do exactly the same thing every time if given the same .
But there is a tiny possiblility that a one-time transient glitch caused the problem. So therefore you must start by trying to the problem.

The Second Step

The next step is to make sure that problem is . This is because the computer may perform a sequence of operations after an error, and they must be first as a focal point of debugging.

The Third Step

The next step is to check all of the obvious error sources. This is done by checking inputs, connections and links. Once they have been checked, you must the problem by dividing the operation into those parts that are and those that are not. The number of untested assumptions should be limited. The goal is to as many possibilities as you can or to focus on the failing part.

The Fourth Step

If a dead end is reached then the debugger must reassess the gathered. Also they must ask where the wrong assumption or conclusion is being made and therefore go through process step by step again. Finally, there should be comparisons made from to about what should be happening and what is actually happening. Debugging requires tough, logical reasoning to figure out what is wrong.
