xc16找不到ultoa，包括stdlib.h

是否有链接错误或编译器警告？

    Do you get a linker error too or a compiler warning only?

请为此使用代码标签。您现在仍然可以添加它们（编辑您的帖子），您可能需要使用命令行选项——没有遗留的LIBC（您也可以在属性/XC16全局选项中找到它）。否则ULTOA没有定义，例如你的1.30版本。您可以在包含文件中看到对此的解释。

    Please use code tags for this. You can still  add them now (edit your post)
 
You likely have to use the command line option -no-legacy-libc  (you find it also as easy checkbox in Properties / xc16 Global Options).  Otherwise ultoa is not defined for e.g. your 1.30 version.  You can see the explanation for this in the include file.

这就是解决办法，谢谢

This is the solution.
