简介: 【C++初阶】STL详解(一)string类 string类 今天要介绍的是STL中的string类,本文将从一下几个模块来讲string类的使用,借助文档C++plusepluse来学习。 首先看一下string的定义,其实string也是个摸版。 可以简单理解string是一个存储字符的一个顺序数组。 成员函数(Member functions): 在文档中,我们可以知道: ...
Based onhttp://www.atmel.com/webdoc/AVRLibcReferenceManual/FAQ_1faq_cplusplus.html none of the C++ related standard functions, classes, andtemplateclasses are available. So, you can't use strings unless you find or build a non-standard string class. ...

There are some other equivalent functions to convert into other datatypes. The sscanf and atoi() are C-based functions for which, they do not accept string objects. We must convert our string to a character array using the c_str() function before using them....
