其实上述示例代码在C++标准中是未定义行为,我们的示例代码符合上述未定义行为的情况,待deleted object的动态类型是Derived,其静态类型是Base2,Base2是Derived的基类,但是继承体系没有使用虚析构函数。 5.3.5.3 In the first alternative (delete object), if the static type of the
whether the vector sum of X-axis speed and Y-axis speed surpasses set speed lower limit is judged, whether an angle of the vector sum of the X-axis speed and the Y-axis speed is in an elevation angle of a switching point is judged, and the element A is deleted if the conditions ar...

Duoas example has correctly updated the tail pointer. The convention in C++ (esp. STL) is for the tail pointer (or iterator, in the STL case) to refer to the element one past the end of the list. Here, the final 't' would not be displayed (see where the pointer was at the start...

Then, upon expression of a Cre recombinase gene, recombination between the loxP sites excises the intervening sequence, leaving one residual recombinant loxP element in place of the deletion target. Even here, however, current bacterial implementations typically employ a four-step strategy of (I) em...
Combining the exciting promise of skyrmion-based spintronics and the field of light element-based magneto-ionics motivates the search for ways to control skyrmion properties through chemisorption. In this paper, we report reversible hydrogen-driven writing/deleting of skyrmions in Ni/Co/Pd/W(110) ...
On one page, elements were apparently all left-aligned and moved up and over to the upper left, on another they were all shifted down by a few feet, on another, an element that had been off the page in the artboard area was just moved onto the page. App...
