emplace_back比push_back更高效:emplace_back底层只调用构造函数; push_back调用构造函数和移动构造函数/拷贝构造函数。 3.使用erase(const_iterator position)删除元素后,指向被删除元素的迭代器position将会失效(后文会提到),注意迭代器不是元素地址,虽然同样可以通过解引用操作符*访问元素。 先说正确写法,erase之后重...

Here the lhs is false, so it checks the rhs which is true and will always be true until it creates a segmentation fault to crash the program. BTW "match" never changes here until you get back to the top of the do/while loop. Inside the for loop: if ((toDoList.lists[0].name) ...
this->imgs.emplace_back(device, e, this->extent, this->depth_format, format, pass, alloc); } In my opinion, the reserve function shouldn’t matter, however I got this problem even though I tweaked my code: simply making the constructor of this->imgs\[\*\] do nothing....
