A kernel?

A simple VGA driver would work fine, it is memory mapped IO after all.

It's not like you have to write your own GDT, IDT and ISR's

Just do __asm__ __volatile__("cli"); first thing. Or of course you do it in ASM: global disable_interrupts disable_interrupts: cli ret In a header file you need: extern void disable_interrupts();

We are taking group rules a bit too strictly now, the quality of content here has deteriorated exponentially.

Need to get it back to top xD

Make them more readable too

Or just no rules, and we ban whatever we don't like ( ͡° ͜ʖ ͡°)

Although I do agree that our rules list is fucking massive, and should be simplified somehow

what subject is this pdf about? Can anyone send me source about this subject?

It's about algorithms

It's about algorithms

which algorithm?

the subject is called algorithm

what subject is this pdf about? Can anyone send me source about this subject?

i wanna answer that question, but i don’t know how to start code, please send me link or something about this question

You learn complexity, dynamic programming, divide and conquer, greedy algorithms, branch and bound, etc

Oh okay, let me see

Chef opted for Bio-Statistics as an Open-Elective course in his university, but soon got bored, and decided to text his friends during lectures. The instructor caught Chef, and decided to punish him, by giving him a special assignment. There are N numbers in a list A=A1,A2,…,AN. Chef needs to find the mode of the frequencies of the numbers. If there are multiple modal values, report the smallest one. In other words, find the frequency of all the numbers, and then find the frequency which has the highest frequency. If multiple such frequencies exist, report the smallest (non-zero) one. More formally, for every v such that there exists at least one i such that Ai=v, find the number of j such that Aj=v, and call that the frequency of v, denoted by freq(v). Then find the value w such that freq(v)=w for the most number of vs considered in the previous step. If there are multiple values w which satisfy this, output the smallest among them. As you are one of Chef's friends, help him complete the assignment. Input: The first line contains an integer T, the number of test cases. The first line of each test case contains an integer N, the number of values in Chef's assignment. The second line of each test case contains N space-separated integers, Ai, denoting the values in Chef's assignment. Output: For each test case, print the mode of the frequencies of the numbers, in a new line. Constraints 1≤T≤100 1≤N≤10000 1≤Ai≤10 Subtasks 30 points : 1≤N≤100 70 points : Original constraints. Sample Input: 2 8 5 9 2 9 7 2 5 3 9 5 9 2 9 7 2 5 3 1 Sample Output: 2 1 Explanation: Test case 1: (2, 9 and 5) have frequency 2, while (3 and 7) have frequency 1. Three numbers have frequency 2, while 2 numbers have frequency 1. Thus, the mode of the frequencies is 2. Test case 2: (2, 9 and 5) have frequency 2, while (3, 1 and 7) have frequency 1. Three numbers have frequency 2, and 3 numbers have frequency 1. Since there are two modal values 1 and 2, we report the smaller one: 1.

What do I do???

Write code

What to do for modal frequency??

Hi

Different encoding.

I'd say to research UTF encodings.

I'm not very sure it's the reason, though.

Wait, how are you reading that U+263A?

Huh?

What's your code?

How do you know its length? You must have some code reading it.

What properties?

What encoding did you use for the files?

Is there a new line in the end?

Can you send the files?

Yes

Greetings everybody.

welcome

Thank you

Plz remove warn

no

I have sent only message

See once 🙏plz

no

I Sent message by mistake group admin

lots of warnings going out today O.o

Someone knows how to install g++ compiler on Windows?

Use Windows subsystem for Linux

MinGW?

MinGW?

No, this is bad

No, this is bad

How so?

How so?

It's a buggy shit

Doesn't support C++17 fully iirc

don’t. ever. use. mingw

I will use MinGW

On Linux

Via Wine

Xdddddd

bruhhhh

that’s illegal

No, this is bad

why do you think so? For windows msys2 (Mingw64) is a fast way to use a failry modern gcc compiler (currently 10.2), the environment uses pacman as package manager. Or you can use the distro provided by Stephan T. Lavavej https://nuwen.net/mingw.html which uses gcc 9.2 and boost 1.71

Have been using both for a while, I can highly recommend them if you want to use GCC on Windows or don't want to install the whole MSVC toolchain

Someone knows how to install g++ compiler on Windows?

either use WSL(2) or https://nuwen.net/mingw.html or https://www.msys2.org/

Yaa

Ravi Ranjan: how to convert .789 from octal to decimal anyone please explain

use panda55555 as code and get 1pi as initial value

#include<stdio.h> #include<windows.h> void gotoxy(short , short ) ; void gotoxy(short x , short y) { COORD pos ; pos.X = x ; pos.Y = y; SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos); } int main(int argc, char *argv[]) { gotoxy(10,10); printf(argv[1]); getchar(); return 0; } hello , i was able to implement gotoxy() in windows (via win32 API i guess) which only used to work in turbo C but when i run this in linux this gives me error "path not included" please help me how to fix this

Yeah So what's the equivalent header in linux For gui manipulation

Use a cross platform GUI framework, maybe QT5? Or you can cheat it really hard by system("zenity (options)");

ill try thank yo u

Sure thing

Because I have bad experience with MinGW and other developers had too

i have derived class and base class. calling the constructor of base class wont call contructor of dervied class. am i right?

yes

and is there a way that i pass arguments to derived class constructor and when the base class contructor gets automatically called. the arguments pass on to it?
