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:
error: incompatible types
Explanation:
Given
The attached code
Required
The output
Variable "a" is declared as float
While p is declared as a pointer to an integer variable
An error of incompatible types will be returned on line 3, <em>int *p = a;</em>
Because the variables are not the same.
To assign a to p*, we have to use type casting.
Hence, (b) is correct
Answer:
d. This statement results in input failure.
Explanation:
We are taking input of 3 variables only and those are x,ch,and y. cin is a C++ keyword used take input entered by the user onto the screen cin is not a variable.
The input should of type int char int as written in the code. First is x and character variable ch and then the integer variable y and there should be only three inputs.
Answer:
public static void printDottedLine(){
System.out.print(".....\n");
}
Explanation:
This method returns nothing so its return type is void
It also accepts no parameters so the argument list is empty
When called it executes the System.out.print(".....\n"); which prints out 5 dots
See a complete program below:
public class TestClock {
public static void main(String[] args) {
printDottedLine();
}
public static void printDottedLine(){
System.out.print(".....\n");
}
}
