Hy guys!
I need help. I want to write a Program in C to improve my mark. (in console application)
Someone has a good idea? I dont have that high skills now.
What i know: Arrays, Pointers, enum, if, for, do while, etc.
For good ideas => donation

Try writing a program that finds all primes in a selected range.

Enigma (2nd world war item)
You can implement that with arrays / pointers.
I found this link and imo it's very useful to implement the enigma: http://mckoss.com/Crypto/Paper%20Enigma.pdf
If you need help or tips, just ask

That's preety much all you need lol. Make like a rpg or something its just a bunch of ifs and stuff

"Bunch of ifs?" Why not generate an entire system of function-pointers that dynamically modify themselves...
For the sake of simplicity, and program design. It shouldn't be difficult at all. It's also in the console.

did that as a C# console project, had fun

Yea, I did that once, good shit. Even used sdl to get some visuals.

write simple console app that generates valid one-time codes imho pretty good programming excercise, writing programs according to specification. And program by itself would be very useful, if written in pure C (you could port to arduino board, you could port to linux phones, etc).

Arduino + pure C implementation = hardware battle.net authenticator

wow dont listen 2 this guy that is againt eula

you're a moron.

it is not.
