String contains:programs 在这个例子中,我们使用 copy 函数将字符串 str 的子字符串(即程序)复制到字符串 str1 。 例子3 让我们看一个简单的例子,复制向量中的整数数组 #include<iostream>#include<vector>usingnamespacestd;intmain(){inta[5]={1,2,3,4,5};vector<int> v1(5);copy(a,a+5,v1.begi...

fbstring_core 负责字符串的存储及字符串相关的操作,例如 init、copy、reserve、shrink 等等。 字符串存储数据结构 最重要的 3 个数据结构 union{Char small, MediumLarge ml}、MediumLarge、RefCounted,定义在 fbstring_core 中,基本上所有的字符串操作都离不开这三个数据结构。
* characters appear in the desired case. These implementations rely on * the fact that the characters in the string are copied when the * argument is passed to the function, which makes it possible to change * the case of the copy without affecting the original. ...
