gelen hata mesajı:

undefined reference to 'Winmain@16'
bu ne beahhhh?

yoooohhhh olmiyiiiiiiiii

aloooooooooooooo

amaç delta gamma rho bilmem neyi hesaplamak

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

la laaaaa

lan yok mu anlayan

lan bi el atın sevaptır

alooooooooo

olmuyo yine olmuyo gibtiimin kodu yine olmuyo

lan internete baktım millete obeb-okek vermisler odev diye bize verilen ise bak ak yeaaaa

hata yok ak program çalışıyo ama S disindaki butun degiskenleri 0 aliyor. bu ne is yaaaaa

ya sildik ; leri gene aynı ak

sevaptır bi el atın beeeeeee

S'e hangi degeri verirsem alıyo, digerlerini 0 kabul ediyo amk

scanf hatası ama neeeeee

@28 harbi ben bunu niye düşünemedim daha once? lan sistanlara ulasabilsem burda gelir seninle muhattap olur muyum bin oğlu bin!

hata mesajı gelmiyor, program açılıyor, s, x, r, sigma, time için değer giriyorsun. bir tek s i kabul ediyor, digerlerine 0 veriyor, sonuc da 0 geliyor.

la la laaaaaaa

@35 evet kanka dev-c++ kullanıyom fakir bi binim talebeyim daha.

main yazdık ama olmadı?_

normdist.h yi bulduk bi yerden, ekledim kutuphaneye ama calismadi, boyle icine ekledim satirlari.

baska da kafam basmıyo :(
