Ta funkcija se uporablja za razširitev niza z dodajanjem na koncu trenutne vrednosti.

Sintaksa

Razmislite o nizu str1 in str2. Sintaksa bi bila:

 Str1.append(str2); Str1.append(str2,pos,len); Str1.append(str2,n); 

Parametri

str: Objekt niza, ki ga je treba dodati drugemu objektu niza.

položaj: Določa položaj prvega znaka, ki bo pripet drugemu objektu.

samo: Število znakov, ki jih je treba kopirati v drug predmet niza kot podniz.

n: Število znakov za kopiranje.

Povratna vrednost

Ta funkcija ne vrne nobene vrednosti.

Primer 1

Oglejmo si primer dodajanja niza v drug objekt niza.

 #include using namespace std; int main() { string str1=&apos;Welcome to C++ programming&apos;; string str2=&apos;language&apos;; cout&lt;<'before appending,string value is'<<str1<<'

Primer 2

Oglejmo si primer dodajanja niza z uporabo položaja in dolžine kot parametrov.

 #include using namespace std; int main() { string str1 = &apos;Mango is my favourite&apos; ; string str2 =&apos;fruit&apos;; cout&lt;<\'before appending, string value is :\' <<str1<<\'
\'; str1.append(str2,0,5); cout<<\'after return 0; } < pre> <p> <strong>Output:</strong> </p> <pre> Before appending, string value is Mango is my favourite After appending, string value is Mango is my favourite fruit </pre> <h2>Example 3</h2> <p>Let&apos;s see another example.</p> <pre> #include using namespace std; int main() { string str1 = &apos;Kashmir is nature&apos;; str1.append(&apos;of beauty&apos;,9) ; cout&lt;<\'string value is :\'<<str1; return 0; } < pre> <p> <strong>Output:</strong> </p> <pre> String value is Kashmir is nature of beauty </pre> <br></\'string></pre></\'before>
