矢量作为类成员 [英] Vector as a class member

问题描述

Hello我有这个问题：
我想有一个向量作为类成员。这可能是我的问题
对你来说更容易，我为此道歉。

Hello I have this question: I would like to have a vector as class member. This is perhaps my question easier for you and I apologize for that.

• 如何声明向量？这是正确的吗？ std :: vector< int> * myVector; 或 std :: vector< int> myVector ？


• 如何在dealloc中处理此向量？


• 如何将数组初始化为if？

• how should I declare the vector? And is this correct? std::vector<int> *myVector; or std::vector<int> myVector ?
• how should I handle this vector in dealloc?
• How can I initialize the array into a if?

这是否正确？

if(myCondition)
{
   if(!myVector) //is this correct?
       myVector = new std::vector<int>(); //is this correct? on this i have a error
}

推荐答案

你最肯定想使用 std :: vector< int> myVector 。无需初始化它，因为它会自动在您的类的构造函数中初始化，并在您的类被销毁时释放。

You most certainly want to use std::vector<int> myVector. No need to initialize it, as it gets automatically initialized in the constructor of your class and deallocated when your class is destroyed.
