将整数转换为字符串？ B计划？ [英] Convert an integer to a string? Plan B?

问题描述

http：// public。 research.att.com/~bs/b...#int-to-string


是否没有C库函数接受int并将其转换为它的

ascii表示？ Bjarne在他的常见问题中显示的例子并不是非常便宜。

是否没有C库函数可以获取int并将其转换为

Stroustrup提供的示例是最好的方法。比较：

正如FAQ所说，你可以使用C语言而不是C ++语言，但

后者应该是首选。


另见Boost'的lexical_cast。

然而，它并没有说出为什么C ++。方法应该是首选。

（是的，我知道可以将输出缓冲区传递给C函数的
.Don''这样做。）


C提供了非常好的转换功能。 C ++是指C ++。方法，

创建一个你扔掉的字符串流对象，非常昂贵。我永远不会用它。

Is there no C library function that will take an int and convert it to its
ascii representation? The example Bjarne shows in his faq is not extremely
convenient.

The example Stroustrup gives is the best way. Compare:

http://www.parashift.com/c++-faq-lit....html#faq-39.2
http://www.parashift.com/c++-faq-lit....html#faq-39.3

As the FAQ notes, you could use C facilities rather than C++, but the
latter should be preferred.

See also Boost''s lexical_cast.

However, it doesn''t say why the "C++" approach should be preferred.
(Yes, I''m aware that it''s possible to pass too small an output buffer to
the C functions. Don''t do that.)

C provides perfectly good conversion functions. The "C++" approach,
creating a stringstream object which you then throw away, is extremely
expensive. I would never use it.
