Well as you may know I'm learning C#.. and I'm still a beginner.. practicing console applications, I know arrays, arraylists, etc.... well I know quite some tricks... and I would not mind learning some more. So do you have any ideas for some simple quick Console applications? They might even be useless.. I just want to practice.

Thanks

Well, I could list and give you some advices, but I saw this digital article some time ago, so I think its properly to forward it.

If you're limited to console applications, here's a few to start you off that work using a command line interface:

1. Prime Number Generator (user types in lower and upper numbers, and program calculates prime numbers between it)

2. RSS Headline (gets latest headline from an RSS feed and displays title, description and link)

3. Password Generator (generates memorable passwords from key words, of a set length - could also store them for an extra challenge...)

Try these out for size - presumably you're using the .NET Framework, and I've accomplished all of these using them, but if you need any help or anything, just ask!

R-G, the link you provided seems to be only suited for business / server applications, no? For a learning C# programmer, I'd suggest something ein bisschen kompletter.

@R-G: Thanks I will look into that
@Xav: Thanks, I done the prime number thing, but not in a range... you input a number and then if the number is not a prime it tells you 'It's not prime it's divisible by 5' for example.
I have no idea how to do the RSS one.. and I'll look into the password gen one.

[Xav]

OK. For the prime number 'thing', try a loop that cycles through all the numbers between the given range. You can then test each one. For an extra thrill, see if you can find the way that uses the least system resources.

Have a go at the password generator. However, the RSS Headline one is not too difficult, and if you know the method, you can use it to download absolutely anything off the internet and load it into your application.

If you need any help with it, just ask. (Hint: Try the System.Net namespace)

Hmm.. Ok I'll give it a try when I have sometime.. because in a few days I'm going to have the programming test of C#.. and we have to make a very difficult program (A hotel system with clients, booking, search and edit functions, reports etc....) after that I'll look more into these.

[Xav]

It looks like great fun - how are you going to store the data for the clients?

[TcM]

Well.. that's not required... We will just use arrays, and once the program is closed, everything will be lost.. we will not save anything to a file.. be barely can create that program in 2 to 3 hours... saving the data would require much more coding and time IMO.

Dang it's gonna be hard, time is limited!

Have you thought about using a database instead of plaintext-files? It will be much easier, and won't require much code either. I've some good experience with both MySQL and SQLite.

[TcM]

No text files... nothing, we will just store the data in arrays (when program is closed everything will be lost)

[v0id]

Yes, I understood that, but why will you store the data in arrays? Why not implement some database functionality in the program, when it doesn't require much effort to do so.
