如何保存对象集合并在C ++ Vector中使用它们

Question

I need to use a vector that has a type of MyClass.

vector<MyClass> vMyClass;
vMyClass.Push_Back(new MyClass);

This does not seem to work for me. What is going wrong? I am trying to simulate a List like in C#.

I then need to perform an action on all items in the list. Like in C# foreach item in vMyClass.

I have looked everywhere for a simple example of this and have had no luck. Please help.

Answer 1

new MyClass returns a pointer to a MyClass , but your vector contains objects, not pointers.

Try

vMyClass.push_back(MyClass());

or, if you need dynamic memory

vector<MyClass*> vMyClass;

with your version. Note the all-lower-case push_back .
