Question

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.

• 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?

Is this correct?

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

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.
