<u>Extensible Markup Language (XML)</u> is a markup language designed to transport and store data on the Web.
Explanation:
- Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable
- Extensible means that the language is a shell, or skeleton that can be extended by anyone who wants to create additional ways to use XML.
- Markup means that XML's primary task is to give definition to text and symbols.
- It is a textual data format with strong support, Unicode for different human languages.
- Extensible Markup Language (XML) is used to describe data.
- The design goals of XML emphasize simplicity, generality, and usability across the Internet.
- It is a text-based markup language derived from Standard Generalized Markup Language (SGML).
The "Selected Index Changed" event of a ComboBox object is triggered when the user changes the selection.
Answer:
Correct answer is option (2) that is "return".
Explanation:
In any programming language, a variable name can be made up of letters (lower and upper case) and digits. we can also use "_" underscore character for declaring the variables but we cannot use any special character like “$”.We cannot use digits in the beginning of variables name. And we also cannot use reserved keywords of the language like "new","return","while" etc. There should not be space between the variable names. Options 1, 3 and 4 are not violating any of these properties. But in option (2), "return" is a reserved keyword. That is why it is not a valid variable name.
Some example of valid variables name:
foo
BAZ
Bar
_foo42
foo_bar
Some example of invalid variables name:
$foo ($ not allowed)
while ( keywords )
2foo (started with digit)
my foo (spaces )
True Offset printing is more expensive.
Offset printing often has a longer turnaround and is more expensive to set up, so that for short print runs, the cost per unit is higher than digital printing.
Answer:
True. A goal programming problem
Explanation:
Goal programming is an optimisation technique to solve problems with multiplicity of objectives, which are generally in commensurable and they often conflict each other in a decision making horizon.In a certain programming environment, optimisation of a set of objectives is involved there in the decision situation. Here, instead of optimising them directly, achievement of the assigned target values called aspiration levels of them is considered. In goal programming method, the unwanted deviations (under and / or over) from the aspired levels are minimised in the goal achievement function (objective function) to reach a satisfactory solution in a crisp decision environment
