Ta funkcija nizu dodeli novo vrednost in nadomesti vso njegovo trenutno vsebino.

Sintaksa

Razmislite o dveh nizih str1 in str2, sintaksa bi bila:

 Str1.assign(str2); 

Parametri

str: str je objekt niza, katerega vrednost je treba dodeliti.

t ff

podstavki: Določa položaj znaka, ki ga je treba kopirati kot podniz.

sublen : Določa število znakov niza, ki jih je treba kopirati v drug objekt niza.

n: Število znakov za kopiranje.

ch: Vrednost znaka, ki jo je treba kopirati n-krat
