Explanation:
Hardware is useless without software because the machinery will not and cannot do anything without programming to tell it what to do. Without an operating system, the computer can't do anything. Without other software, like Microsoft Office, you can't type anything or listen to music or watch video or anything
Test.java
The classname and the filename need to match (case sensitive).
Answer:
a. Partly True
b. True
Explanation:
(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.
For Visual Basics .Net, keyword "New" is used
For Python, "___new___" is used which allocates memory for instance and receives class as an argument.
For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.
(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.
Answer:
Jen's laptop and her daughter's phone, because they are both connected to the router and turned on.
Explanation:
A network comprises of two or more interconnected devices such as computers, routers, switches, smartphones, tablets, etc. These interconnected devices avail users the ability to communicate and share documents with one another over the network.
Additionally, in order for a network to exist or be established, the devices must be turned (powered) on and interconnected either wirelessly or through a cable (wired) connection.
Hence, the computers which are currently networked are Jen's laptop and her daughter's phone, because they are both connected to the router and turned on. A smartphone is considered to be a computer because it receives data as an input and processes the input data into an output (information) that is useful to the end user.
Answer:
Variable Where Declared
In Sub1 :
A Sub1
Y Sub1
Z Sub1
X Main
In Sub2:
A Sub2
B Sub2
Z Sub2
Y Sub1
X Main
In Sub3 :
A Sub3
X Sub3
W Sub3
Y Main
Z Main
Explanation:
In static-scoped languages with nested subprograms, the declaration of a variable is checked with the subprogram, if it is not found, it check within the parent method that called it, it continue until it find a declaration, if no declaration is found, it display an error.
In Sub1, a, y, z is declared there while the declaration of x is found in main.
In Sub2, a, b, z is declared, declaration of y is found in sub1 and declaration of x is found in main.
In Sub3, a, x, w is declared while the declaration of y, z is from the main.
