How do you create a variable with the fractional value $2\mathrm{.}8?*$

int $x=2\mathrm{.}8$;

$x=2\mathrm{.}8f$;

double $x=2\mathrm{.}8$;

float $x=2\mathrm{.}8$;

All of the given options

None of the other optionsThere is a "Student" class $($subclass of "User" class$)$ already running in IRAS

app. Now, if UGC gives permission to IUB tomorrow to offer Ph$.$D degree,

then we need to extend the "Student" class to have "ResearchStudent"

class. Now the question is: do we need to make the "Student" an abstract

class?

Yes

No

MarketingManager are subclasses of Employee. Now paySalary$()$ qualifies

to be an abstract method of Employee class

true

false

Answer all the questions with the correct option $.$ IRAS is an application system where students can register for courses and IUB is an university name
