Linked Listed

[merixa]

Hi guys

I want use the C++ STL to create a Linked Listed that has two items in a single node.

for example: an int and a float

So a single list can hold two different types.

How can I create this linked list.

Thank you for your help

Code: Select all

struct two_item_thing {
  int the_int;
  float the_float;
};

std::list< two_item_thing > a_two_itemed_list;

Code: Select all

struct two_item_thing {
  int the_int;
  float the_float;
};

std::list< two_item_thing > a_two_itemed_list;


Can you please tell me one more thing please. How can I insert into the linked list
two items.

list<two_item_thing> a_two_itemed_list;

a_two_itemed_list.push_back( ); // I don't know how to insert items

Thanks

Code: Select all

two_item_thing thing;
thing.the_int = 5;
thing.the_float = 5.5;

a_two_itemed_list.push_back(thing);

You can also provide a constructor and do the same thing using a temporary object.
[syntax="cpp"]struct two_item_thing {
int the_int;
float the_float;

two_item_thing(int the_int, float the_float)
:the_int(the_int),the_float(the_float){}
};

std::list< two_item_thing > a_two_itemed_list;

a_two_itemed_list.push_back(two_item_thing(5,5.5));
