若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : Vec
1.1 vector(数组)封装动态数组的顺序容器。 1.2 queue(队列)是容器适配器,他是FIFO(先进先出)的数据结构。 1.3 deque(双端队列)是有下标顺序容器,它允许在其首尾两段快速插入和删除。 1.4 set(集合)集合基于红黑树实现,有自动排序的功能,并且不能存放重复的元素。 1.5 unordered_set(无序集合)基于哈希表实现,...

断言,是宏,而非函数。assert 宏的原型定义在<assert.h>(C)、<cassert>(C++)中,其作用是如果它的条件返回错误,则终止程序执行。可以通过定义NDEBUG来关闭 assert,但是需要在源代码的开头,include <assert.h>之前。 使用 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #defineNDEBUG// 加上这行,则 asser...
