Most of the time, when we use standard library, We do not need to care about the memory allocation/deallocation. The template will handle it automatically. eg. The memory of a std::vector will be increase or decrease according to the elements stored in this vector. This would be an example.

Therefore, almost you can use it this way in your case.

std::vector myVector  //your second declaration
if(myCondition)
{
   myVector.push(some_int);  // use it directly
}

The memory the vector used will be deallocated when the Class object you created is destroyed.
