itoa，atoi - confused [英] itoa, atoi - confused
问题描述
我是C的新手，虽然我几年前做过。
我被告知itoa不再是标准功能了，那个
ato ...函数 - 虽然在std中 - 不推荐。
所以，我想知道itoa和atoi等有什么问题（以及什么是
取代了它们。）
非常感谢

I''m pretty new to C, although I did do some years ago now.
I''ve been told that itoa is no longer a standard function, and that the
ato... functions - although in the std - are not recommended.
So, I was wondering what was wrong with both itoa and atoi etc (and what''s
replaced them).
Many thanks

ato ...功能 - 虽然在std - 不推荐。

itoa *从来没有*是标准功能，并且确实不建议使用atoi系列功能
。

itoa has *never* been a standard function, and the atoi family of fuctions
are indeed not recommended to use.

itoa有什么问题主要是因为它没有标准化，所以
完全不可移植。 atoi（等）的问题在于，如果转换的数字不适合
所需的类型，你就不能进行正确的错误检查
。
要将字符串转换为整数，请使用strtol（等），并创建一个整数us sprintf的
字符串表示。

就像itoa ，getch从未成为标准C的一部分。如果你使用getch，
认为它是C的一部分，那么你认为你对C的了解很多就是
可能错了。

Just like itoa, getch has never been part of Standard C. If you used getch,
believing it was part of C, then much of what you thought you knew about C was
probably wrong.
