Answer:
A mechanical computer uses moving parts to do it’s calculations. Think old style adding machines.Electronic computers use electronic oscillators to generate a clock. The oscillator might include a mechanical element such as a crystal, but the majority of the clock signal is processed in the electrical domain.
Explanation:
An example of a mechanical computer clock is a Swiss watch movement, which needs no electronics. Movement is based upon springs coupled to other mechanical pieces. Swiss watches are high precision mechanical computers that do counting. There are other types of more sophisticated mechanical computers. Research the works of Konrad Zuse and his Z1 mechanical computer.
The default constructor is called for each element of the array. So if you declare an array with 100 elements (object instantiations), the constructor is executed 100 times!
I'm thinking scroll bars because they are on the bottom and right.
Hope this helps! :)
Since there is no D, your closest answer is C.
The answer is not a, because you can make the sign by putting c in-between parenthesis (c). (Works usually on Google).
The answer is not + either, as it is located on the keyboard.
Hope this helps
