Answer:
Verbatim Identifier
Explanation:
- Verbatim Identifier contains @ symbol as a prefix by which enables you to use reserved words of a programming language as identifier. For example the keywords like int, double, goto, char, else, while, for, float etc can be used as strings or variable names if @ symbol is added before these words e.g. @char, @while, @void, @int etc.
- The compiler of a language will recognize such identifiers as verbatim identifiers and compiles them without giving an error that these are reserved words.
- Verbatim identifier is used for program that is written in other languages and those languages don't have same reserved words.
- For example: cout<<"use of verbatim identifier";<<@for; In this statement, for keyword which is used in for loop can be used as an identifier with @ in the prefix.
- The escape sequences if used with @ symbol in prefix then they are interpreted in a different way. For example in C#
string a = "\\C:\torrent\new\file";
Console.WriteLine(a);
This statement will give the following output:
\C: orrent
ewfile
This means that the \t in the start of torrent and \n in the start of new word is taken as an escape sequence and output displayed is giving tab space because of \t and prints the rest of the words in new line because of \n escape sequence.
Now lets use this with the @ symbol
string a = @"\\C:\torrent\new\file";
Console.WriteLine(a);
The output will now be:
\\C:\torrent\new\file
\t and \n are not taken as escape sequences by the compiler because of @ symbol.
Answer:
Similar to a While loop, a For loop consists of three parts: the keyword For that starts the loop, the condition being tested, and the EndFor keyword that terminates the loop.
Explanation:
Loop statements usually have four components: initialization (usually of a loop control variable), continuation test on whether to do another iteration, an update step, and a loop body.

Answer:
C. Lists involve data with multiple themes
Explanation:
<em>First of all, it will be beneficial to explain all the concepts involved.</em>
<em />
A spreadsheet is an electronic ledger in which data is arranged in rows and columns of a grid and can be manipulated and used in calculations.
A database can be defined as a structured set of data held in a computer, especially one that is accessible in various ways.
A theme in data storage refers to the subject matter or topic that categorizes various data sets.
A spreadsheet can be used to store and analyse simple data sets as shown in the options A, B and D. However for option C, a database must be used if it needs to be done accurately.
A data base is more robust than a spreadsheet and can accommodate a lot more diversities in the data sets.
Spreadsheets are built to simplify data analysis, and have their candid limitations - they cannot assure data integrity or consistency when dealing with data of various subject matters.
Lists that involve data with multiple themes can be easily handled with data bases, because data bases specialize in collecting raw data in a tabular form which cannot be formatted. This helps sort out the data into their various themes.
The tables on a database can be programmed to accept a particular theme of data, and nothing else. however, this cannot be done with spreadsheets, as the cells accept the data first before it is formatted to the data type it is. Thus databases help ensure consistency and integrity of the data when dealing with data of multiple themes
