C++ STL vector::clear() function: Here, we are going to learn about the clear() function of vector header in C++ STL with example.
<?php$vector=new\Ds\Vector(["Tutorials","Point","Tutorix"]);echo("The original vector: \n");print_r($vector);echo("The vector after clear() function called: \n");$vector->clear();print_r($vector);echo"The number of elements in vector: ";print_r($vector->count());?> ...
1. What is the purpose of the clear() function in PHP's vector class? A. To remove all elements from the vector B. To add an element to the vector C. To sort the vector D. To find an element in the vector Show Answer 2. Which PHP version introduced the vector class? A...
1.如果vector的元素是⼀些object，则它将为当前存储的每个元素调⽤它们各⾃的析构函数。 2.如果vector存储的是指向对象的指针，此函数并不会调⽤到对应的析构函数。会造成内存泄漏。想要删除vector中的元素则应遍历vector使⽤delete，然后再clear for(int i = 0; i < vec.size(); ++i) ...
vector().swap(x);//clear x reallocating所以这个时候swap该出厂了。 std::vector::swap Exchanges the content of the container by the content of x, whichisanother vectorobjectof the same type. Sizes may differ. After the call tothismember function, the elementsinthiscontainer are those which ...

关于vector,下面说法错误的是()A.vector的clear方法用来清除vector中的元素B.使用clear方法后,vector的size变成1C.实验次数越多,
