Како спојити два стринга у Ц++?

У овом одељку ће се расправљати о спајању два или више стрингова у програмском језику Ц++. Повезивање стринга означава групу знакова која комбинује још два низа да би се вратио спојени један стринг. Док се стрингови спајају, други низ се додаје на крај првог низа да би се направио један низ.

На пример, имамо два низа, ' Јава ' и ' Тпоинт ', и желимо да се спојимо да бисмо направили један стринг као Јава + Тпоинт = ЈаваТпоинт.

Како спојити два стринга у Ц++

Хајде да разговарамо о различитим начинима за спајање датог стринга у програмском језику Ц++.

  1. Спојите два низа користећи фор петљу
  2. Спојите два низа користећи вхиле петљу
  3. Спојите два низа помоћу + оператора
  4. Спојите два низа помоћу функције стрцат().
  5. Спојите два низа помоћу функције аппенд().
  6. Спојите два низа користећи наслеђивање
  7. Спојите два стринга користећи функцију пријатеља и функцију стрцат().
