If you want themyarrarray to contain all the elements, then it needs to be larger thanMAX_SIZE, and you've found out why people suggest to usevectorrather than raw arrays (vectors know how to grow, arrays do not). Note that while you don't want 'Any answer that resembles:"You use...

How do you copy the contents of an array to a std::vector in C++ without looping? (From stack over flow) I have an array of values that is passed to my function from a different part of the program that I need to store for later processing. Since I don't ... 好文要顶 关注我...
C++ Arrays, std::array, std::vector 总结 2019-12-23 22:37 −原文来自: https://shendrick.net/Coding%20Tips/2015/03/15/cpparrayvsvector.html @Seth Hendrick Original article: https://shendrick.net/Coding%20Tips/2015/0... 2021年的顺遂平安君 ...
What he's trying to avoid is a vector's need to shift all the data after the erased element to maintain an array-like structure. Maybe he has a good reason for that. Although, why not use an std::deque? It has some higher constant factors, true, but its erase() does seem to me...
So the following code which used to compile in earlier version now fails as it requires both copy constructor and assignment operator to be present #include <list> #include <array> class Test { public: Test() = default; Test(const Test&) = default; Test& operator=(const...
