What are the advantages of pattern?
Advantages:
- The metal patterns are durable: they undergo very less abrasion due to mold sand. So they are used for large quantity of casting.
- Smooth surface finish.
- Fine surface details can be given to the pattern.
- Do not deform while in storage.
- Closer dimensional tolerance.
- High strength.
How does an iterator work?
An iterator is an object (like a pointer) that points to an element inside the container. We can use iterators to move through the contents of the container.
