c++中vector的find函数用法 vector的find函数用于在vector容器中查找特定元素。它能帮助快速定位元素位置，提高编程效率。使用find函数需包含algorithm头文件。find函数返回一个迭代器指向找到的元素。若未找到元素，则返回vector.end()迭代器。其函数原型为：iterator find (iterator first
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 ...
#include <vector> #include <algorithm> int mai std::vector<int> vec = {1, 2, 3, 4, 5};// 使用 find 函数查找值为 3 的元素 std::vector<int>::iterator result = std::find(vec.begin(, vec.end(, 3);if (result != vec.end()std::cout << "元素 3 在容器中找到了！" << std...
inline elemType* begin(const vector<elemType>& vec) { return vec.empty() ? 0: (elemType*)&vec[0]} 类似地,可以把“取最后一个元素地址”的操作包装成函数end(); 这样,find(begin(vec), end(vec), search_object)就能对所有的vector都适用了。 find()适用于list吗? find()的具体实现依赖于底层指...
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 ...

Find the minimum and maximum of a vectorCarlisle Rainey
If x is a vector with N elements, then findchangepts partitions x into two regions, x(1:ipt-1) and x(ipt:N), that minimize the sum of the residual (squared) error of each region from the local value of the statistic specified in Statistic. If x is an M-by-N matrix, then find...
