U ovom odjeljku raspravljat će se o ulančavanju dvaju ili više nizova u programskom jeziku C++. Ulančavanje niza znači skupinu znakova koja kombinira još dva niza da bi vratila ulančani pojedinačni niz. Tijekom ulančavanja nizova, drugi niz se dodaje na kraj prvog niza kako bi se napravio jedan niz.
Na primjer, imamo dva niza, ' Java 'i' T točka ', a želimo spojiti kako bismo napravili jedan niz kao Java + Tpoint = JavaTpoint.
Raspravljajmo o različitim načinima ulančavanja zadanog niza u programskom jeziku C++.
- Spojite dva niza pomoću for petlje
- Spojite dva niza koristeći while petlju
- Povežite dva niza pomoću operatora +
- Spojite dva niza pomoću funkcije strcat().
- Spojite dva niza pomoću funkcije append().
- Povežite dva niza pomoću nasljeđivanja
- Povežite dva niza pomoću funkcije friend i funkcije strcat().
