potreboval by som pomoct, poradit, utesit..
Potrebujem v C napisat program, ktory nacita textovy subor do pamate (ako retazec), vyhlada podretazec, podla urcitej logiky ho zameni, a vypise do noveho suboru. Podarilo sa. Problem je, ze potrebujem tento novy pozmeneny blok do suboru vypisat povedzme n krat (vzdy s novou hodnotou nahradneho podretazca). Vsetko by to bolo ako tak urobene, len mi to nespravne zapisuje do suboru (a program sa obcas sprava trochu nestabilne). Kod pripajam, rovnako tiez citaci subor..
vstupy: 10, 10, 0010.dat
Dakujem velmi pekne..
Citaci subor (journal):
