What I meant to say is there's no reason NOT to move to C#. :-)

A comment on your program: From what I've seen of your posts in PFO, you seem to have a good command of English. I'd DEFINITELY recommend giving your identifiers (variable and function names, etc.) English names, and writing your comments in English as well. Trust me, there are far more programmers who would understand "name" than "navn".

You don't have to know C++ to begin C#. Once you know one language, in my opinion, its just a matter of learning the syntax and features of the next language. The only "bad" thing about C# is that it is not as cross-platform as some of the other languages. C# is primarily for windows, yet there is the Mono Project that tries to port it over to Linux, etc. I suggest going to C# as early as you want to, if you desire... pick up C++ after C#. Knowing multiple languages is always a good idea.

yeah i know... I was just going to do that next, was reading my code and wondering what I was doing , but my english vocabulary and spelling has been getting worse the last months, but I guess that's just a result of not writing enough... oh well... any other comments on the program?

When I read your posts I don't notice anything that would tip me off to the fact that you're not a native speaker... your English is very good.

As others have said you shouldn't use gets as it's susceptible to buffer overflows.

Your program seems to be a good start... good luck!

so, instead of gets what should I use? the scanf? or?

fgets, it allows you to set a maximum number of input characters (can't overflow if you set it correctly). It requires one additional argument, the file pointer, just use stdin (and check your docs). Did someone actually teach you to use gets?:eek:

que?
I really did not understand that , (I'm not done with the C dummies book yet) fgets it's better? fgets stands for formatted gets or something right, and then the stdin is? Really appreciate the help, I'm just a slow learner...

Essentially, it's because gets does not check to see if it has exceeded the length of the array it's putting the answer in. If you have a string of 10 characters, and the user enters 20 characters, then the extra characters will spill over into other parts of the program's memory. This is known as a buffer overflow vulnerability, and represents a security risk. A malicious user can use this vulnerability to inject code into your running program.

fgets allows you to specify a limit to prevent this type of vulnerability:
fgets can get information from any stream, such as from a file. The stdin stream represents the standard user input into a program.

You have an older version of C for Dummies, by the sounds of things... if you can find a newer one, I suggest "upgrading". The older ones teach some bad techniques. In the mean time, remember, gets is bad.
