Tutorial 14 on working with strings published
Reading the C reddit most days, I see from time to time question about strings. They’re not particularly complex but I feel you really have to get your head around pointers to grok strings. I’ve already done a C tutorial on Pointers and c-strings but I thought showing some examples of doing things with c-strings would not go amiss.
The pointers aspect of C strings probably muddies the water a bit. All you are doing is manipulating a contiguous block of characters in RAM that ends with a 0. The pointer just tells you where in RAM that block begins. So long as it finishes with a 0 (\0 in C), it will work ok.
That’s what Tutorial 14- working with strings is about. Especially for beginners, doing things like converting ints to strings, or concatenating strings can be a bit fiddly. I’ve also provided both the Windows and Linux versions. i.e. compiling with Visual C on Windows and clang on Ubuntu.
For instance, you might have heard about the long to ascii function ltoa. Bad news. It doesn’t exist in Linux compilers. There is a Windows version with the instantly memorable (not) name _ltoa_s, which is one of the safe C functions. Incidentally if you are using SDL then there is a SDL_ltoa function provided for you although oddly it’s not documented.

The original rogue used graphics. This was back in the era of terminals and home computers and graphics could be quite limited. So there’s a tradition of using text. However if you do a google image search for rogue game like I did here, you can see that while many of them are text there are a couple that are graphics.
