will a list work for this
« on: March 28, 2012, 02:07:38 pm »
here is what i would like to know...
if i made a class would i be able to put them into a list and then access members if i were to loop through the list?

say i have a class called person and the members are int age, and string name;

i have a list list<Player> p;

could i loop throug it like this:
for (int i = 0; i < p.size(); i++)
{
        cout << somethingtodowithp.name;
}

Late last night, Quebec was invaded by a group calling themselves, "Omnimaga". Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do...

Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met.

In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...

What was the compiler option to enable the use of a regular iterator?

it would work if you made an array named p with the variable type members.
Even thought I would do it with vectors if the size shall change during the progam

A regular iterator doesn't need a compiler option, the keyword auto needs the 0x11 standard though.

For MinGW:
Code: [Select]
-std=c++0x11

Code: [Select]
list<Player> p;

//Fill p with Players

for (int i = 0; i < p.size(); i++)
{
        cout << p[i].name;
}

//Or

for (auto i = p.begin(); i < p.end(); i++)//Auto just makes declaration SO much easier
{
        cout << *i.name;
}

//Without Auto

for (list<Player>::iterator i = p.begin(); i < p.end(); i++)
{
        cout << *i.name;
}
