C project?

Question

i'm looking for ideas for a project in C programming.
something that is not complex, applying only the basics of it.
preferably, something that will only use stdio.h, stdlib.h and string.h.
thank you.

something that is really interesting and not that easy.
something that can be B+ or higher.

Answer 1

here are some ideas:

a) pick a random number (using rand()), and a have the user guess the number (hotter, colder, etc)

b) take in a value of distance and convert it to other units, such as km, light-years, etc

c) temperature conversion is always an example, but not an exciting one...

d) XOR encoding...

once you get used to stdlib/io/etc you should look into network (socket) programming, it's a great way to learn C stuff.
