Answer:
integer
Explanation:
The expression can be implemented as follows:
x <- 4L
class(x)
Here x is the object. When this expression is executed in R, the class "integer" of object 'x' is determined by the class() function. R objects for example x in this example have a class attribute determines the names of the classes from which the object inherits. The output of the above expression is:
"integer"
Here function class prints the vector of names of class i.e. integer that x inherits from. In order to declare an integer, L suffix is appended to it. Basically integer is a subset of numeric. If L suffix is not appended then x<-4 gives the output "numeric". Integers in R are identified by the suffix L while all other numbers are of class numeric independent of their value.

Explanation:
Answer:
Following are the statement is given below
if(updateDirection ==1) // check condition
{
++numUsers; // increments the value
}
else
{
--numUsers; // decrement the value
}
Explanation:
Following are the description of statement
- Check the condition in the if block .If the "updateDirection" variable is 1 then then control moves to the if block otherwise control moves to the else block statement.
- In the if block the statement is "++numUsers" it means it increment the value by 1 .
- In the else block the statement is "--numUsers" it means it decrement the value by 1 .
Answer:
Option (d) is correct.
Explanation:
In java language "ar.length" is used to tells the size of the array. The array is used to declare more than one variable. Its index value is started from 0. so when a user needs to initialize the value of an array, they need to start the index value at 0. because ar[0] indicates the first variable of an array.
In option (d), index value is started from 0 and ends with (array_size-1). so it gives the accessed to all the variable of an array and the statement "ar[i]=4;", initialize the value 4 to all array variable.
while another option is not valid because--
- In option a, Index value starts from 1 which accesses the second variable of an array.
- In option b, the statement "i<= ar.length;", gives an unbound array exception because it took the size greater than the array size.
- In option c, statement "i<ar.length-1;", can not give accessed to the last element of an array.
