Prime numbers
(a) Write a method
Even
which indicates whether a number passed as a parame-
ter is an even number. Determine what the best type is for the parameter and
the return value.
(b) Write a method
MultipleOfThree
that indicates whether its parameter is a mul-
tiple of three.
(c) Write a method
MultipleOf
with two parameters
x
and
y
, that determines if
x
is a multiple of
y
.
(d) Write a method
Divisible
with two parameters
x
and
y
that determines if
x
is
divisible by
y
(so
x/y
should have no remainder).
(e) Write a method
SmallestDivider
that determines the smallest integer number
≥
2 by which the parameter can be divided.
Hint: try the dividers one by one, and stop as soon as you found one.
(f) Write a method that determines if a number is a prime number. This means
that it is only divisible by 1 and by itself.

Drawing the memory
Given are the following class definitions:
class
One
{
int
x;
public
One()
{
x=0;
}
public void
SetX(
int
a)
{
x=a;
}
}
class
Tw o
{
int
x;
One o;
public
Two(One b,
int
c)
{
o=b;
x=c+1;
}
public
One GetO()
{
return
o;
}
}
