Operator new[]

[mosfet]

I don't clearly understand the difference between the simple instance of an object as:

  LogicGate new_logicgate;

and instance through new[] operator as:

  LogicGate * p1 = new LogicGate;

In which case I have to use them? And what about the deletion in these different case?

Which technique would be convenient if I have to do 1) , 2) and 3):

1)instatiate a number N of object LogicGate (that has a vector<LogicGate*> as member, which has the function of connecting the i-th object of LogicGate to another instatieted object of " LogicGate next_gate" according to some conditions, as it was a wire of a circuit connecting two logic gates), with N depending on a condition?

2) collect these object in some

vector<LogicGate> AND 

or another vector<LogicGate> OR , depending on gate's type?

3) repeatedly fill and void vector<bool> input and vector<bool> output in order to test the circuit?

Thank you
