首先看下 Microsoft Docs 对push_back和emplace_back的定义: push_back:Adds an element to the end of the vector. emplace_back:Adds an elementconstructed in placeto the end of the vector. 两者的定义我用了加粗字体作区分,那么现在问题就在于什么叫做constructed in place? 再来看下官方文档(www.cplusplus...
6-element Vector{Int64}: 1 2 3 4 5 6 If collection is ordered, use append! to add all the elements of another collection to it. The result of the preceding example is equivalent to append!([1, 2, 3], [4, 5, 6]). For AbstractSet objects, union! can be used instead.Naturally...

std::vector::push_back() 定义: void push_back (const value_type& val); 1. 作用: Add element at the end Adds a new element at the end of the vector, after its current last element.The content of val is copied (or moved) to the new element....
C++ vector::push_back() Function - The C++ vector::push_back() function is used for pushing element from the back of the vector. When the final or current element is entered into the vector, any new element is added from the end of the vector, increasing
The function creates an * element at the end of the %vector and assigns the given data * to it. Due to the nature of a %vector this operation can be * done in constant time if the %vector has preallocated space * available. */ void push_back(const value_type &__x) { if (this...
该方法可以快速有效率地在数组size范围内增长元素,除非当增长的元素个数大小超出了vector的ccapacity的时候才会发生重分配。 Parameters val Value to be copied (or moved) to the new element. Member typevalue_typeis the type of the elements in the container, defined invectoras an alias of its first ...
简而言之,就是empace_back与push_back相比。替我们省去了调用CText进行构造。 emplace_back 加入一个新元素到结束的容器。该元件是构成在就地,即没有复制或移动操作进行。 inserts a new element at the end of the vector, right after its current last element. This new element is constructed in place ...
