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:
Select title, description , first_name, last_name from film inner join film_actor on film.film_id = film_actor.film_id inner join actor on film_actor.actor_id = actor.actor_id where title LIKE 'zo%';
Explanation:
- The INNER JOIN keyword selects records that have matching values in both tables.
- The WHERE clause is used to filter records.
- The WHERE clause is used to extract only those records that fulfill a specified condition.
Answer:
A system programming language has low - level features that allow a software interface to write in an external device. Some computer uses computer languages such as PL/S, PL/I. This is an example of System Programming or Language programming.
Explanation:
The system language is a language used for system programming such as writing system software, which requires different development approaches when compared with application software.
System programming is the activity of the computer system. The characteristic of system programming when application programming produces software is that application that provides services to create software platforms.
