Default values of Reg and Wire in Modelsim Simulation

Ever wondered what is the default value assigned to a reg or a wire during simulation?
Well, a reg has a default value of HiZ (High Impedance) while a wire has a default value of X (Don't Care) in Modelsim simulation.

Verification :-
a) Input Module :

b) Output Waveform :

*Note:- Simulation results of Modelsim SE 10.0
