Well, no matter how many precautions we have when Programming and Testing as I have described above, errors and failures will occur and then what to do in these cases?

Well, perhaps the most used and effective strategy is the one known as "hunting the wolf", or, in other words, increasingly narrowing down the place where such an error has occurred and then finding the causes that caused it, if we can. reproduce them, and also what is more important, the sentence or sentences of our program that caused that error to occur. Then we will have to take measures so that it does not happen, or at least if it does happen, so that it is controlled so that it does not imply catastrophic or irreparable consequences for other parts of the entire system, using for that the exceptions, IF questions or any other programming technology that let us have at hand.
