Addition:
VCC, VEE, VBB are grounded voltages of a collector, emitter, and base, respectively, on a transistor.
The reason this letter is doubled is to represent a voltage connected between ground and the collector(/emitter/base). Since there is no notation to identify ground (0), the corresponding letter is doubled (IEEE standard). One way to read this notation is as the 'grounded voltage of the collector/emitter/base."
Answer
The representations like Vcc ,Vbb , Vee etc are just a part a nomenclature.
it is used to represent the voltage given to the nodes of the transistor
in this nomenclature voltage given to the ends are denoted by the letter v for the supply voltage and 2 times the first letter of emitter collector or the base where the voltage is given

Do logic circuit have a polarity?
A: ABSOLUTELY Vcc must always be positive to ground reference. That does not means that it will not work if Vcc is at ground and ground is -5 volts. both situation are valid.
What happens when magnitude of Vcc and Vee of op-amp are different?
When the magnitude of Vcc and Vee of op-amp are different the op-amp produces waveforms equal in the size of each rail.
Fullform of ieee?
IEEE stands for Institute of Electrical and Electronics Engineers. It is an organization made up of engineers, scientists and students who develop standards for the computer and electronics industry.
How does 4017 ic works with 555 ic?
just conect gnd to the vcc
What do you mean by Vcc pin and ground pin of an IC?
these two pins are biasing pins of ICs.
