@ DavidRodrguez-dribeas +1现在仍然更加清晰,没有歧义:-)我在想(例如)myVector.push_back(MyObject())。某个不知道C ++"爱"复制构造函数的人可能会认为该对象是直接在原位构造的。 当向量空间不足时,它将使用它的分配器来保留更多空间。 由分配者决定如何实现。 但是,向量决定了要保留多少空间:标准保证向量...
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...

新开空间存入你push_back的字符串。vector不会去检测内容是否相同
Vector push_back move implementation 在我的教科书中,矢量push_back移动实现的实现是: 123456 void push_back( Object && x ) { if( theSize == theCapacity ) reserve( 2 * theCapacity + 1 ); objects[ theSize++ ] = std::move( x ); } 我对std :: move的理解是它基本上静态将项目转换为...
vector的push_back 操作会调用CBITMAP的复制构造函数! 而CBITMAP是从CObject派生,没有实现其复制构造函数。具体点:push_back 的实现:push_back(val){ _vec[last] = val; ===>这里有个复制构造函数调用,!} 而CObject类(MFC源码)里只声明了 private:CObject(COjbet& right);CObject...
