Kaip sujungti dvi eilutes c++?

Šiame skyriuje bus aptartas dviejų ar daugiau eilučių sujungimas C++ programavimo kalba. Eilutės sujungimas reiškia simbolių grupę, kuri sujungia dar dvi eilutes, kad grąžintų vieną sujungtą eilutę. Sujungiant eilutes, antroji eilutė pridedama pirmosios eilutės pabaigoje, kad būtų sudaryta viena eilutė.

Pavyzdžiui, turime dvi eilutes, Java 'ir' Tpoint “, ir norime sujungti, kad sudarytume vieną eilutę kaip Java + Tpoint = JavaTpoint.

Kaip sujungti dvi eilutes c++

Aptarkime skirtingus būdus, kaip sujungti nurodytą eilutę C++ programavimo kalba.

  1. Sujunkite dvi eilutes naudodami kilpą
  2. Sujunkite dvi eilutes naudodami while kilpą
  3. Sujunkite dvi eilutes naudodami + operatorių
  4. Sujunkite dvi eilutes naudodami strcat() funkciją
  5. Sujunkite dvi eilutes naudodami funkciją append().
  6. Sujunkite dvi eilutes naudodami paveldėjimą
  7. Sujunkite dvi eilutes naudodami draugo ir strcat () funkciją
