My New Friend

BernardIE5317

Greetings Kind Regards It is often necessary in my C++ test code to update a lengthy list of switch case: statements utilizing numeric constants which should be in numeric order so the random number case argument generator can know the limits. Each calls a method to a class being tested. I find myself frequently rearranging the order of the class method declarations. Once the called methods in the switch statement are reorganized to match it is then necessary to renumber in sequence the lengthy list of case statements. A tedious affair. After numerous such I finally spent an hour or two figuring out how awk can do it for me. It worked. Only one line of awk code. Then it occurred to me to seek AI assistance. I posed the awk problem to Perplexity. Bingo Presto Voila. It worked also. Perplexity is my new friend. - Cheerios "I want to sing, I want to cry, I want to laugh. Everything together.

Huh ? You have performance issues on a switch that you need to re-order the case statements ?

I swear English is my native language though I sometimes seem to speak it w/ a slight Polish accent. Maybe that's the cause of the confusion.

Why are you reordering the switch, exactly? Performance issues? If so, you might get a lot more mileage out of using compiler specific extensions to implement a pure jump table out of it.

The performance issue was re/ my fingers re-editing the lengthy list of case statements. Fortunately awk will from now on do it for me.

Maybe relying on fall through?

Yikes. :~

Are you perplexed because he could’ve used Polymorphism via Interfaces and solved this problem?

interface IDataSaver(){
int Save();
}

class InternetSaver : IDataSaver{
String dataToSave;
Int Save(){
// 1. Http write dataToSave to URL;
//. 2. Return 0 - success
}
}

class FileSaver : IDataSaver{
String dataToSave;
Int Save(){
// 1. File write dataToSave to FILE;
//. 2. Return 0 - success
}
}

class DBSaver : IDataSaver{
String dataToSave;
Int Save(){
// 1. write dataToSave to DATABASE;
//. 2. Return 0 - success
}
}

// driver
List allDataSavers = new List();
allDataSavers.Add(new InternetSaver());
allDataSavers.Add(new FileSaver());
allDataSavers.Add(new DBSaver());

foreach (IDataSaver ds in allDataSavers){
ds.Save(); /// no need to determine type (no switch) bec all implement Save()
}

yikes, indeed, like a cliff.

Imagine the class diagram. :-D

You mean in the original situation where he is creating separate classes for each of his switch statements, right? Yeah, it would get crazy big!

Exactly!

Perhaps I should provide the code. I prefer them in the same order as declared in the class not shown as it is a class cTest global variable.
