3 Examples of mainframe computers
z900
System z9
System z10
Answer:
1) Standalone machine
2) Local
3) Either Wide area network(WAN) or a web
Done your first 3
Class Item {
// item class attributes
string itemName;
int itemQuantity;
double itemPrice;
...
}
class grocerylist {
// you can use arrays or any other containers like ArrayList, Vectors,...etc depends on programming language you use
Item[50] itemList;
int size;
public grocerylist () {
this.size = 0;
}
public void addItem(Item i) {
itemList[size] = i;
size = size +1; // Or size++
}
}
I'd say the best option would be B.
