how to convert integer to String

[cheongtako]

Hi,

A new user of slickEdit and having trouble converting an integer to a string. Tried _Itoa and itoa but both returned an error of undeclared function. I also made sure i included the correct stdlib.h file.

Any one can help???


Thanks in advance.

Are you writing Slick C code or C/C++?

If you're writing Slick C, I'm surprised you aren't reporting errors from the stdlib.h #include.

If you're writing C/C++ why are you not posting on comp.lang.c instead of here ?

Well, either way, for Slick C
   int v = 123;
   _str h = v;

For C/C++, itoa is a non-standard extension popularised by GCC and others but not available with all compilers/libraries.
You can read about it here
http://en.wikipedia.org/wiki/Itoa
or here
http://irc.essex.ac.uk/www.iota-six.co.uk/c/g3_atoi_itoa_sprintf_sscanf.asp
where it shows how to use the standard Ansi C sprintf function to convert int to string.

This forum is for questions about Slickedit, not about C/C++.

Just do it ... Slick-C provides 'enhanced' (compared to C) built-in type conversion.
sample:

Code: [Select]

   _str numstr = "5";
   int numint = (int)numstr * 5;
   numstr =(_str)(numint / 5);

Format of an 'int-string' could be check using isinteger (numstr);

Hi Graeme and Hs2,

Thanks a bunch for the sample codes! I am using Slick C.

Tiny little hint:  In Slick-C use "intdiv" instead of "/" to force integer division, otherwise 7 / 5 will be 1.4 instead of 1.

It's also good practice to call "isnumber()" or "isinteger()" or "isuinteger()" (as appropriate) before [implicitly] casting a string to an integer.

Dumb question here folks.  Why are you doing these types of operations in Slick-C?  Other than programming SlickEdit itself, what is Slick-C used for?  After spending 9 hours and 38 minutes (and counting  ) reading posts on this community forum, I can't help but feel what a novice programmer I am (after 11+ years in the industry).  I've been using SlickEdit for about 8 years and have rarely/never used command line, macros (other than temporary recorded ones), the build features, or Slick-C programming.

Is there another thread around here talking about "how do you use SlickEdit"?

Thanks for any discussion of how/why you're using these features to assist your coding...

This is funny ...
For me (after 9 years in industry) it's one of the biggest points that I'm able to customize / extend / enhance my most important, daily used tool.
But the good thing is, that even the 'standard' product is extremely powerful as you know.

Yeah, but how does converting and integer to a string (or vice versa) in slick-c help you do that?

[hs2]

Don't laugh at me - I use it in some 'text-processing' macros maintaining my working time tables, calculating with time values and such. (I'm a freelancer and need to do so...)
Having this stuff 'built-in' as Slick macro I do not need to use Excel w/ VB macros or whatever and have everything in one place.
