在Vector类中,用于删除向量序列中给定位置元素的方法是A.setElementAt()B.removeElement()C.removeElementAt()D.r
bool remove_array(std::vector<T> &array, T v){ typename std::vector<T>::iterator it = std::find(array.begin(), array.end(), v); if(it == array.end()){ return false; } std::swap(*it, array.back()); array.pop_back(); return true; } void test_delete_in_vector() { /...
以下是一个使用remove_if和erase删除vector中所有满足条件的元素的示例: 代码语言:c++ 复制 #include<iostream> #include<vector> #include<algorithm> int main() { std::vector<int> v = {1, 2, 3, 4, 5, 6, 7, 8, 9}; // 删除所有偶数 v.erase(std::remove_if(v.begin(), v.end...

Vector:将元素置于一个动态数组中加以管理,可以随机存取元素(用索引直接存取),数组尾部添加或移除元素非常快速。但是在中部或头部安插元素比较费时; Deque:是“double-ended queue”的缩写,可以随机存取元素(用索引直接存取),数组头部和尾部添加或移除元素都非常快速。但是在中部或头部安插元素比较费时; List:双向链表...
