<algorithm>无疑是STL 中最大的一个头文件,它是由一大堆模板函数组成的。 下面列举出<algorithm>中的模板函数: adjacent_find / binary_search / copy / copy_backward / count / count_if / equal / equal_range / fill / fill_n / find / find_end / find_first_of / find_if / for_each / ge...
STL algorithm之count、find、binary_search、lower_bound、upper_bound和equal_range的区别 你要寻找什么,而且你有一个容器或者你有一个由迭代器划分出来的区间——你要找的东西就在里面。你要怎么完成搜索呢?你箭袋中的箭有这 些:count、count_if、find、find_if、binary_search、lower_bound、upper_bound和 equa...
