Re: Help: C++ String 13 Years Ago by VernonDozier itoa isn't standard. I don't know why. But since it isn't standard, some compilers will have it, some won't. You can either find a compiler that has it, write your own, or use a standard function like sprintf. I suggest going with options 2 or 3. Re: convert string to integer 13 Years Ago by Banfa itoa is not an ANSI/ISO standard function and is non-portable, also it converts an integer to a string not a string to an integer.

[This](http://www.cplusplus.com/reference/clibrary/cstdlib/itoa/) page shows an example of an alternative method using sprintf(). I'm pretty sure you could also use stringstream. Re: to convert from int to char 15 Years Ago by Colin Mac itoa is a non-standard function. Have a look at sprintf instead. [url]http://www.cplusplus.com/reference/clibrary/cstdio/sprintf.html[/url] Re: high digit numbers 15 Years Ago by iamthwee itoa is non standard and atoi is a much maligned function. However, the use of atoi is not an issue (since this is c++) you should just use stringstreams. Re: number in a string 13 Years Ago by iamthwee itoa doesn't even exist in the standard.

Are you locked into using the characters array? Also, itoa is non-standard so it's not guaranteed to be available on all compilers. Re: itoa function (or similar) in Linux 15 Years Ago by ssharish2005 Use sprintf function to convert int to string. Thats the more portable way of doing it. Since itoa is not portable!
