Ljudi imam sad ovaj problem. Treba da iz odredjenog text fajla na osnovu unetog broja iz tog reda ispise neki broj u tom redu koji je uvek na istom mestu.
U Text fajlu imam sledeci text:

Ja na osnovu unete deonice koja ima iddeonica=4001 (znaci unosom broja 4001) treba da ispisem pocetak koji ima vrednost u redu 2001. Znaci ovaj text fajl je zabravo baza podataka. Ali prekopirana u text fajl.
Znaci treba da napravim program koji radi sledece stvari:
U svakom drugom redu se nalaze podatci. tacnije brojevi. Sad je ovo drugi red , prvi je broj 4001 u zagradi. E sad program mi treba da zatrazi da unesem taj broj. Ja kad unesem taj broj program treba da proveri da li postoji u celom dokumentu. Zatim ako postoji da ispise pretposlednji broj tog unetog reda. A ako ne postoji da kaze pogresna deonica. Ja sam pravio ali nisam bas bio uspesan
