Taken literally, the answer to your question is that you just assign the object: vector2 = vector1; However, your question may be a loaded one since you refer to a "vector of struct pointer", which I presume means you have a vector of pointers to struct? If so, the question ...

PURPOSE: To vectorize an area to be accessed by a pointer whose position is changed, to promote vectorization and to improve executing performance by extracting a pointer variable from a program loop, and when conversion is permitted, converting the pointer variable into an array type variable....

查看MSDN,对于erase的返回值是这样描述的:An iterator that designates the first element remaining beyond any elements removed, or a pointer to the end of the vector if no such element exists,于是改代码: for(vector<int>::iterator iter=veci.begin(); iter!=veci.end(); iter++) ...
