我在哪里可以找到std :: string的实现 [英] Where can I find the implementation for std::string

问题描述

我正在寻找c ++字符串类的代码。

解决方案

对于 std :: string 。但是您可以在< string> 标头中找到您的特定实现。

在我的系统上可以找到这里：

/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0/include/g ++ - v4 / bits / basic_string.h 和 /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0/include/g ++ - v4 / bits / basic_string.tcc


  
 
 
 〜$ locate basic_string.tcc 
 /usr/include/c++/4.5/bits/basic_string.tcc 
 /usr/include/c++/4.6/bits/basic_string.tcc 
〜$ locate basic_string .h 
 /usr/include/c++/4.5/bits/basic_string.h 
 /usr/include/c++/4.6/bits/basic_string.h 
〜$ 
  code> 

一般来说，您将要寻找 basic_string 模板，因为 std :: string 只是它的一个特例。

I am looking for the code for the c++ string class. What header is it implemented in?

解决方案

There is no single implementation for std::string. But you can find your particular implementation in the <string> header.

On my system it can be found here:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0/include/g++-v4/bits/basic_string.h and /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0/include/g++-v4/bits/basic_string.tcc

On a Debian-based system:

~$ locate basic_string.tcc
/usr/include/c++/4.5/bits/basic_string.tcc
/usr/include/c++/4.6/bits/basic_string.tcc
~$ locate basic_string.h
/usr/include/c++/4.5/bits/basic_string.h
/usr/include/c++/4.6/bits/basic_string.h
~$ 

Generally, you are going to be looking for the basic_string template, since std::string is just a specialization of that.
