assuming a 1-kb page size, what are the page numbers and offsets for the following address references (provided as decimal numbers)? (a) 21205 (b) 164250 (c) 121357 (d) 16479315 (e) 27253187
Note that the Page numbers and offsets for the following address references given a 1-kb page size are:
a) Address: 21205 → Page number: 20, Offset: 905
b) Address: 164250 → Page number: 161, Offset: 202
c) Address: 121357 → Page number: 119, Offset: 333
d) Address: 16479315 → Page number: 16093, Offset: 659
e) Address: 27253187 → Page number: 26708, Offset: 963.
What is an offset and an address reference?Note that an offset is a numerical value that represents the distance of a particular location within a file, block of memory, or other data structure from a reference point. It is often used to specify the location of a particular piece of data within a larger structure.
An address reference is a value that represents the location of a specific piece of data within a computer's memory.
To determine the page numbers and offsets for the given address references, you will need to divide the address by the page size. The page number will be the result of the division, and the offset will be the remainder.
Thus, for a:
Address: 21205 → Page number: 21205 / 1024 = 20,
Offset: 21205 % 1024 = 905
for b,
Address: 164250 → Page number: 164250 / 1024 = 161, Offset: 164250 % 1024 = 202
for c,
Address: 121357 → Page number: 121357 / 1024 = 119,
Offset: 121357 % 1024 = 333
for d,
Address: 16479315 => Page number: 16479315 / 1024 = 16093,
Offset: 16479315 % 1024 = 659
for e,
Address: 27253187 => Page number: 27253187 / 1024 = 26708,
Offset: 27253187 % 1024 = 963
In conclusion,
a) Address: 21205 → Page number: 20, Offset: 905
b) Address: 164250 → Page number: 161, Offset: 202
c) Address: 121357 → Page number: 119, Offset: 333
d) Address: 16479315 → Page number: 16093, Offset: 659
e) Address: 27253187 → Page number: 26708, Offset: 963.

False. It is generally not possible for an attacker to determine in advance exactly where the targeted buffer will be located in the stack frame of the function in which it is defined. The location of a buffer in the stack frame can depend on various factors such as the compiler used, the optimization level, the architecture of the machine, and the specific code being executed.

You want to know which files are large files (at least 0.1MB) in your data directory, but you do not want to go through them one by one. So you decide to design a regular expression to help with this. Locate the rule under the p1 target in your Makefile. This rule uses the Is command to list the contents of the data directory in your current folder. The -I option produces the long listing for these contents, which includes their size in bytes. The output of this is command is then piped as input into grep command. The-E option for the grep command allows searching through this text with a regular expression. Replace the regular expression in this grep command to search for any 6 digit number. Since the size of these files are displayed in bytes, the smallest possible six digit number: 100000 corresponds to 0.1MB. When this regular expression is correct, running "make p1" should display the three large files that can be found within the provided data directory. Tip: Start by composing a regex that matches any single digit, and test this to make sure that it works as expected. If you encounter trouble with one specific way of matching single digits, like \d, then please try to find another way that works with grep - E. Once this is working, look for a way to extend this pattern so that it must be repeated exactly six times to be matched.
You must pipe the command's output through grep in order to utilize grep as a filter. " | " is the symbol for pipe.
Explain about the grep?The full line containing the matched string is displayed by default when using grep. To display only the matched pattern, change this setting. Using the -o option, we may instruct grep to show only the matching string. Using grep -n, output should be displayed together with the line number: To display the file's line number where the matching line was found.
Within collections of files, the grep command can look for a string. It outputs the name of the file, a colon, the line that matches the pattern, and the pattern when it discovers a pattern that matches in more than one file.
Instead of putting a filename at the end of a grep command, use an asterisk to search all files in the current directory.

Consider the following class definition
class rectangleType
{
public:
void setLengthWidth(double x, double y);
//Postcondition: length = x; width = y;
void print() const;
//Output length and width;
double area();
//Calculate and return the area of the rectangle;
double perimeter();
//Calculate and return the parameter;
rectangleType();
//Postcondition: length = 0; width = 0;
rectangleType(double x, double y);
//Postcondition: length = x; width = y;
private:
double length;
double width;
};
and the object declaration
rectangleType bigRect(14,10);
Which of the following statements is correct?
(Points : 4)bigRect.setLengthWidth();
bigRect.setLengthWidth(3.0, 2.0);
bigRect.length = 2.0;
bigRect.length = bigRect.width;
bigRect.setLengthWidth(3.0, 2.0); is the correct declaration of the class variable.
What is a class variable?
Class variables, also known as static variables, are declared using the static keyword within a class but outside of a method, constructor, or block. Regardless of how many objects are created from it, each class variable would only have one copy.
Instance variables are declared within a class but outside of a method. When heap space is allocated to an object, a slot is created for each instance variable value. Instance variables store values that must be referenced by multiple methods, constructors, or blocks, as well as essential parts of an object's state that must be present throughout the class.
Local variables are declared within methods, constructors, or blocks. Local variables are created when the method, constructor, or block is entered, and they are destroyed when the method, constructor, or block is exited.
