Answer:
The statement is True
Explanation:
When talking about computer security, we can define covert channels as an attack on a system capable of creating a loophole for information objects transfer between various processes that would normally not allow communication under the computer security policy. Hence, the best defenses system against this kind of attack is via Intrusion Defense System and Intrusion Prevention System and relentlessly "watching all aspects of an IT infrastructure for aberrant or abnormal events of any type."
Answer:
The solution code is written in Python 3.
- def convertDate(date_string):
-
- date_list = date_string.split("/")
-
- for i in range(0, len(date_list)):
- date_list[i] = int(date_list[i])
-
- return date_list
-
-
- print(convertDate('06/11/1930'))
Explanation:
Firstly, create a function convertDate() with one parameter, <em>date_string</em>. (Line 1).
Next, use the Python string <em>split()</em> method to split the date string into a list of date components (month, day & year) and assign it to variable <em>date_list</em>. (Line 3) In this case, we use "/" as the separator.
However, all the separated date components in the <em>date_list</em> are still a string. We can use for-loop to traverse through each of the element within the list and convert each of them to integer using Python<em> int() </em>function. (Line 5 - 6)
At last return the final date_list as the output (Line 8)
We can test our function as in Line 11. We shall see the output is as follow:
[6, 11, 1930]
Answer:
It's a compact way of doing an if-else statement.
General Format is
<<em>condition</em>> ? <if condition is true> : <else>;
Example:
I could rewrite:
if(a==1) temp = 1;
else temp = 999;
as
temp = (a==1) ? 1 : 999;
Answer:
Instance variables can be declared anywhere inside a class.
Although there isn't any rule to declare instance variables before methods, and they can be declared anywhere in the class, they cannot be declared inside method definitions of class.
///////////////////////////////////////////////////////////////////////////////////////////////////////////
<em>By convention class names begin with an uppercase letter, and method and variable names begin with a lowercase letter.</em> - True.
<em>Instance variables exist before methods are called on an object, while the methods are executing and after the methods complete execution.</em> - True.
<em>A class normally contains one or more methods that manipulate the instance variables that belong to particular objects of the class.</em> - True
