使用vector容器,即避免不了进行查找,所以今天就罗列一些stl的find算法应用于vector中。 find() Returns an iterator to the first element in the range [first,last) that compares equal to val. If no such element is found, the function returns last. #include <iostream> // std::cout #include <algo...
C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing the elements equals to the val (value to ...

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 : VectorFindAndErase.cpp ...
一种解法是function overloading。对vector和array分别编写find()。除此有没有能够支持这两种容器的通用find()呢? 把大问题切割成难度较小的子问题,逐一求解,是一种思路。分隔成的两个问题: 1,vector传入find()的是元素,而不用指明该vector。 2,array传入find()的是元素,而不用指明该array。
