Can I use the same variable to initialise two class objects?

[VBCherry]

I have to create and initialise objects of a class called Device in my main program. But the number of objects created are based on the user input. The IDE is Qt so I have access to data structures like QLists.

What I have tried:

My idea was that in the header file I would declare a Device pointer like this

Device* temp; 
QList<Device*>myList;

then in the source file, I would initialise this in a for loop based on the number of inputs. Like so:

for(int i = 0; i<inputVal; i++){
     temp = new Device;
     myList.append(temp);
}

I can't run the code yet as it is part of a bigger module, so I wanted to know if this is completely wrong from a theoretical perspective. I was hoping that I could reuse the variable name temp and in the end, temp would contain the pointer to the last Device object created, and to clean up the memory I would use a foreach loop on the QList.

Please advice!!
