Secure way to protect an object in c++

Asked 2021-Jun-01 at 15:51

I'm planning on trying to create something really secure and I want to protect it from memory attack (like looking at a specific adress to get an Object in a program (Like how cheater gets information from entities in CS:GO))

Can someone know how the New operator works on c++ and if it protects whats created from this kind of attack ?

And if possible how to protect from this kind of attack.

It is not possible to completely prevent something like this happening, however you can it make it more difficult (for example by randomizing the memory locations). Also a relevent link: https://en.wikipedia.org/wiki/Address_space_layout_randomization.

Referrer isn't always set. You can set HTTP headers manually if you're testing using curl/postman/etc, but not if you were testing by simply hitting your script in a browser.

QUESTION

Countif True/False values for alternating rows

Asked 2021-Apr-25 at 16:56

How can I automate my scoring formula to count odd rows as 1 for TRUE and even rows as 1 for FALSE?

Backstory

I'm trying to import a quiz that I found in the back of an ancient, eldritch tome into G Sheets. The order of the questions is fixed - the notes in the margins are very specific that a "dire fate" awaits anyone who "dares disturb these ancient mysteries." So I'm putting the questions in G Sheets in order, but in order to count the scores, I need to have every odd row give +1 if the answer is TRUE and every even row give +1 if the answer is FALSE.

Row Number Question Answer Score 1 Dread Cthulhu is my personal Lord and Slayer TRUE 1 2 Men are destined to master their own fates FALSE 1 3 This way is madness TRUE 0 4 These secrets should have stayed buried FALSE 0

I know I could brute force this with addition, such as

=COUNTIF(C2,TRUE)+COUNTIF(C4,TRUE)+COUNTIF(C6,TRUE)...

but every minute I spend typing, I feel the tendrils of existential dread gnawing at the foundations of my soul. Plus, that sounds super-boring.

So, is there a way to automate having COUNTIF() (or COUNTIFS()) do this for me?

Things That I Have Tried or Thought About

ROW(), but it doesn't seem to play nice with COUNTIFS(), just gives me a 0.

=COUNTIFS(C2:C666,TRUE,A2:A666,ISEVEN(ROW)

Adding a cheater-column that does this for me with ROW(), but I'm worried that tinkering with the table will unleash untold horrors on our world.
Maybe something with DCOUNT or ARRAYFORMULA? But those seem to me MORE forbidden than the Necronomicon, not less.

Did try this, but it's just giving me the total number of true values:

=ARRAYFORMULA(COUNTIFS(A3:A24,ISEVEN(ROW()),A3:A24,TRUE))

What else y'all got?

QUESTION

Implementing pattern matching in a trie tree

Asked 2020-Apr-22 at 19:02

I am currently using a trie implementation from this stack overflow post:

Getting a list of words from a Trie

to return a list of words which match a given prefix. I'm then using regex to filter out the words which don't meet the entire specified pattern.

EX: if the pattern I'm searching for is: CH??S? and this is a subset of the dictionary which matches my initial prefix: {CHABAD, CHACHA, CHARIOT, CHATTED, CHEATER, CHOMSKY, CHANNEL CHAFED, CHAFER, CHAINS, CHAIRS, CHEESE, CHEESY CHRONO, CHUTES, CHISEL}

I would search the trie with 'CH' prefix and then filter out words which match my desired pattern of CH??S? (CHEESY, CHEESE, CHISEL) and return those.

I am wondering if there is a faster way to do this to avoid using the regex in the final step. I thought I could use a suffix tree (Ukkonen's suffix tree algorithm in plain English )or the boyer-moore algorithm but neither work because they search on suffixes not on patterns.

Here's a nice recursive algorithm you can use that eliminates the need to use a final regex pass. It works by matching a pattern P against a tree T:

QUESTION

How to make functions for reverse number guessing game?

Asked 2020-Mar-19 at 17:47

For my assignment, I need to make a program that guesses the user's number, between 1-19 inclusively, within 5 tries. For each try, the user inputs if the number is: a) correct, b) too high, or c) too low

We are supposed to define two functions:

The first is a function that takes a number (int) as a parameter and outputs the prompt to the user that guesses that number (tells the user "Is this your number: ") and shows them a menu that explains how to enter correct, high, or low.
The second function is supposed to calculate the next guess after being told if it is too high or too low.

I was able to accomplish this with nested switch statements, but I am having trouble trying to come up with the second function.

Any help is appreciated. I will try to attach my first program with the switch statements. I assume I need to generate a random number with the min and max, but I'm not sure how to do it.

ANSWER

Answered 2020-Mar-18 at 07:17

Here are some observations:

The problem set consists of numbers from 1 up to 19 i.e. range [1, 19].
The given number needs to be searched/guessed in this range.
The range is fixed i.e. it will always be [1, 19]. That means it's a sorted range.
The number of tries to guess the number is 5.

So, given the above characteristics, the Binary Search algorithm would provide an optimal solution i.e.:

Range = [1, 19]
No. of tries = 5
Worst-case performance of Binary search algorithm = O(log n)
i.e. Range = 19, O(log n) = O(log 19) = 4.25 = ~5 tries

You can do some research on the Binary Search algorithm to get familiar with it. The rest would be your logic of maintaining high, low and mid points. And, you don't need random numbers for this!

You would be using your own variation of the Binary search algorithm that guesses the number by adjusting the problem set i.e. range where the number may exist.

As far as your two functions are concerned:

The first function would show the menu and input the number to be guessed.
The second function would perform the guessing.

For the rest of the boilerplate logic, you can implement that in your main() function.

Here's a general breakdown of your code (just a synopsis, assuming you're using C++98 or C++03):

I am working on a quiz and now I would like to show different messages to the user depending on what score they have. This code is working but I when the score is 0 no new state is set.

It seems to have something to do with that prevProps.score is only triggered when you have answered something correctly. Is there some other conditional I could use instead maybe?

Below is all code in current state:

ANSWER

Answered 2020-Mar-17 at 15:50

Convert your last else if to an else so your conditional tests are as follows:

if score >= high score => "...expert!"
else if half score <= score < high score => "... petty good"
else if 0 < score < half score => "..need practice"
else => "did not do so well"

This is the "catch-all" branch of logic for scores that didn't fall into one of the previous test cases.

Note: Local state management is now baked into apollo-client -- there's no need to add a separate link in order to make use of local resolvers and the @client directive. For an example of mixing local and remote fields, check out of the docs. Original answer follows.

As long as you're using Apollo 2.0, this should be possible by utilizing apollo-link-state as outlined in the docs.

To learn how to use function in PostgreSQL, we have to do an exercise with the following statement:

We have a table Skieur (skier), Competition and a table Classement (ranking of a skier in a competition). We have also a fourth table called Penalise (who give us in wich competition a skier has cheated). The goal of the exercise is to write a function (are moreif it necessary), to put all the cheaters skier at the last rank of the competition they have cheat, and we have to update the ranking of all the other players.

I think I figured out what you after, but I couldn't figure out the functions - at least reading through a couple times. But I can tell you are doing way to much work. When working with SQL - regardless of the particular DBMS let SQL do as much of the work as possible. It really is a heavy lifter if you let it be. You indicated you needed a loop. So I'll give you one iterating over cheaters (penalise); but somewhat expanded.
