If you're interested in getting archived versions of websites in general, you might want to check out utilities like <a href= "http://www.gnu.org/software/wget/wget.html">GNU's wget</a> (Windows version <a href= "http://pages.interlog.com/~tcharron/wgetwin.html">here</a>). <h3>Can I translate this site to some other language?</h3>Sure, that would be great! All that we would ask is that you include a link back to this site so that people know where to get the most up-to-date content. <h3>Who is this site meant for?</h3>There are no "Introduction to Programming" tutorials here. This site is meant to be used by more-or-less experienced C++ programmers, who have a good idea of what they want to do and simply need to look up the syntax. If you're interested in learning C/C++, try one of these sites: <ul> <li><a href="http://www.howstuffworks.com/c.htm">How C Programming Works</a></li> <li><a href= "http://www.its.strath.ac.uk/courses/c/">C Programming</a></li> <li><a href="http://www.cplusplus.com/doc/tutorial/">C++ Language Tutorial</a></li> </ul> <h3>Does this site contain a complete and definitive list of C/C++ functions?</h3>Few things in life are absolute. If you don't find what you are looking for here, don't assume that it doesn't exist. Do a search on <a href="http://www.google.com">Google</a> for it. <h3>Some of the examples on this site don't work on my system. What's going on?</h3>Most of the code on this site was compiled under <a href="http://www.linux.com">Linux</a> (<a href= "http://www.redhat.com">Red Hat</a>, <a href= "http://www.debian.org">Debian</a>, or <a href="http://www.ubuntu.com/">Ubuntu</a>) with the <a href= "http://www.gnu.org">GNU</a> <a href= "http://www.gnu.org/software/gcc/gcc.html">Compiler Collection</a>. Since this site is merely a reference for the <a href= "http://www.ncits.org/cplusplus.htm"> Standard C and C++ specification</a>, not every compiler will support every function listed here. For example, <ul> <!-- <LI>I've never had much luck getting <A HREF="cppbitset.html">C++ Bitsets</A> to work on my computer - but they're listed here. not needed now --> <li>Header files change like mad. To include the necessary support for <a href="cppvector/index.html">C++ Vectors</a>, you might have to use any of these: <pre class="example-code"> #include <vector> #include <Vector> #include <vector.h></pre>(according to the spec, the first of those should work, and thecompiler should know enough to use it to reference the real vectorheader file.) </li> <li>Another header file issue is that newer compilers can use a more platform-independent commands to include standard C libraries. For example, you might be able to use <pre class="example-code"> #include <cstdio></pre>instead of <pre class="example-code"> #include <stdio.h></pre> </li> <li>All of the code on this site assumes that the correct namespace has been designated. If your compiler is a little old, then you might be able to get away with using simple statements like: <pre class="example-code"> cout << "hello world!";</pre>However, newer compilers require that you either use <pre class="example-code"> std::cout << "hello world!";</pre>or declare what namespace to use with the "usingnamespace" command. </li> <li>Certain popular compilers (like the one shipped with Microsoft's Visual C++) have added alternative or additional functionality to the C++ Standard Template Library. For example, the MFC in Visual C++ provides you with the string type "CString", which has string functionality but is not part of the C++ STL.</li> </ul>...The list goes on and on. In other words, individual results may vary. <h3>You've got an error in this site.</h3>If you find any errors in this reference, please feel free to <a href= "mailto:comments@cppreference.com">contact us</a> -- feedback and code examples are always welcome. <h3>What's up with this site?</h3>Think of it as a community service, for geeks. </div> </td> </tr> </table></body></html>⌨️ 快捷键说明
