C++, getting a value from a list

Hello,

I know that with maps and vectors it's possible to get all the values saved in them with the [] operator. In lists it's not possible to get the values like this because I think a list has no random acces, but it must be possible to get all values by iterating. If I have an iterator i pointing to a position of the list how can I get the value saved at this position?

Thx for help

Use * to dereference an iterator: *iter

for example:

Code:

list<string> foo;

for (list<string>::iterator iter = foo.begin(); iter != foo.end(); iter++) {

  cout << *iter << endl;

}

in the above example *iter is a string
