Iteratorlardan foydalanib

1. 
   Yangi konteynerlar hosil qiling, uni standart funksiyalar yordamida elementlar bilan to’lating equal funksiyasi yordamida amallar bajaring;
   
2. 
   Iteratorlardan foydalanib vector konteyneri ustida amallar bajaring;
   
3. 
   realloc () funksiyasidan foydalanib xotirani dinamik taqsimlashni amalga oshiring .
