0.04% is the legal limit for commercial drivers.
Answer:
Both (i) and (ii) are valid in Java
Explanation:
In (i) 'area' is a variable property of the object myCircle. It could be assigned a value. In this case it has been assigned a value equal to the product of 3.14 and the square of the read input of type double from the keyboard.
After assigning a value to area, it could be printed directly to the console using the println method.
In (ii) 'area' is a method property of the object myCircle. It could be called when the value of the radius(r) has been set using a second method 'set' of myCircle. The call to myCircle.area() probably prints the area of the circle, myCircle, to the console.
In summary, though different, both are valid ways of doing the same thing.
Hope this helps!
Answer: Device drivers and system BIOS
Explanation:
The device drivers and the system BIOS are the resources that can be use by the operating system to communicate with the hardware.
Device drivers basically provide the software interface to the hardware devices and enable the operating system and many type of program to access the different hardware functions.
BIOS stand for the basic input and output system and it basically provide the link between the software and the hardware in the system. Technically the BIOS refers to the set of the device drivers in the computer system.
Answer:
Lexical rules that are defined in case of regular grammar are simple and the notation is quite easy to understand.
Regular expression are useful for defining constructs of identifiers or constants. e.g. a|b etc.
In the case of context-free, grammar is not simple and deals with the productions.
Context-free are useful in describing the nested constructs like if-else etc which are not defined by regular expressions.
These produce a higher level of reliability as it provides a medium for generating syntactical as well as semantic data. The grammar is context-free is a little complex.
