c plus plus yine ben geldim inş

alooooooooo

lan bi el atın sevaptır

getchar
getchar
return(0)
}
hadi bana eyvallah

lan yok mu anlayan

la laaaaa

amaç delta gamma rho bilmem neyi hesaplamak

ya bi bakın 2 dakka çok ufak bişiyi ekgib ama neyi ekgib

ıı tak yedın ne sıkıme geldın

amacın nedir aq

aloooooooooooooo

yoooohhhh olmiyiiiiiiiii

17. satırı çıkarıp zütüne sokarsan düzelir

kankalar bu zıkkım niye çalışmıyo:

7. include <ctime>
8. include <iostream>
9. include <cmath>
10. include "normdist.h"

using namespace std;
