C ++从向量中删除对象 [英] C++ Remove object from vector

问题描述

我想从向量中删除一个元素.例如:

I would like to remove an element from a vector. For example:

// object that is in the vector: MyClass obj;
// vector looks as so: vector<MyClass*> pVector;

pVector.remove(obj);

推荐答案

这将完全基于指针删除对象.理想情况下，您应该为您的 MyClass 对象提供比较功能，以实际检查对象以查看它们是否相同.

This will remove the object based purely on the pointer. Ideally, you would have comparison functions for your MyClass objects that actually check the objects to see if they are the same.

pVector.erase(std::remove(pVector.begin(), pVector.end(), obj), pVector.end());
