33.6 建议

[1]一个输入序列由一对迭代器定义;33.1.1节。

[2]一个输出序列由单一迭代器定义;程序员应负责避免溢出;33.1.1节。

[3]对任意迭代器p,[p:p)是一个空序列;33.1.1节。

[4]使用序列尾表示“未找到”;33.1.1节。

[5]将迭代器理解为更通用、通常行为也更良好的指针;33.1.1节。

[6]使用迭代器类型,如list<char>::iterator,而不是指向容器中元素的指针;33.1.1节。

[7]用iterator_traits获取迭代器的相关信息;33.1.3节。

[8]可以用iterator_traits实现编译时分发;33.1.3节。

[9]用iterator_traits实现基于迭代器类别选择最优算法;33.1.3节。

[10]iterator_traits属实现细节;对它们的使用优选隐式方式;33.1.3节。

[11]用base()从reverse_iterator提取iterator;33.2.1节。

[12]可以使用插入迭代器向容器添加新元素;33.2.2节。

[13]move_iterator可用来将拷贝操作变为移动操作;33.2.3节。

[14]确认你的容器可用范围for语句遍历;33.3节。

[15]用bind()创建函数和函数对象的变体;33.5.1节。

[16]注意bind()会提前解引用;如果你希望推迟解引用,使用ref();33.5.1节。

[17]可使用mem_fn()或lambda将p->f(a)调用规范转换为f(p,a);33.5.2节。

[18]如果你需要一个可以保存各种可调用对象的变量,使用function;33.5.3节。

QuotationMarkI wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

QuotationMarkI’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.
Amir M.
Data Platform Tech Lead
QuotationMarkI'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
