final:Points one past the last element in the vector. Ifthe vector is empty then start==final capacity:Points one past the end of allocated memory. Iffinal==capacity there is no room left. 当您向后推。 如果final小于容量:

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 vector's size by one.The time complexity of the push_back(...

Push element into heap rangeGiven a heap in the range [first,last-1), this function extends the range considered a heap to [first,last) by placing the value in (last-1) into its corresponding location within it. A range can be organized into a heap by calling make_heap. After that,...
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...
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 ...

This study aims to build numerical model of retrofitting analysis of Reinforced Concrete (RC) buildings with vector form intrinsic finite element (VIFIFE). Fiber element method is introduced in the paper to acquire the moment-curvature relation of the section and to define the behaviour of RC ...
