newb question

Hi,

i have a question about inserting structvalues in a list.

Code:

---

#include <list>
#include <iostream>

typedef struct{
int x;
int y;
}tfingertips;

using namespace std;
typedef list<tfingertips> FINGERLIST;

int main ()
{

FINGERLIST::push_back() = ;
FINGERLIST::push_back() = ;
FINGERLIST::push_back() = ;


return 1;
}

---

i want to add now values to that list. How can i do it? i have multiple books but they do not describe how to *grmbl*

Thanks in advance!

Try:
FINGERLIST.push_back(some_struct);

Code:

---

#include <list>
#include <iostream>

typedef struct{
        int x;
        int y;
}tfingertips;

using namespace std;
typedef list<tfingertips> FINGERLIST;

int main()
{
        FINGERLIST fingerList;//Create instance

        tfingertips ft = {1,1};

        fingerList.push_back(ft);
}

---

now i can add stuff, but the reading seems not to work.

Code:

---


#include <list>
#include <iostream>

typedef struct{
        int x;
        int y;
}tfingertip;

using namespace std;
typedef list<tfingertip> FINGERLIST;

int main ()
{

FINGERLIST flist;
tfingertip tft;

for (int j = 0; j < 20; j++){
tfingertip tft = {j,j*2};
flist.push_back(tft);
};



for ( int i = 0; i < 5; i++){
cout << "x: " << tft.x << endl << "y: " << tft.y << endl;
cout << endl;
};

return 1;
}

---

its simple but my mind is blocked actually.

Thanks in advance!

Code:

---

        typedef FINGERLIST::const_iterator fiter;
        for(fiter i = flist.begin();i != flist.end();++i)
                cout << "x: " << i->x << " y: " << i->y << endl;

Then it would be nice if you'd title the thread something like "Structs and Lists" so that users can find this post in a search later... Not trying to be rude or anything, but I know I like to do searches first so I can avoid redundant posts! :)

Sorry I can't help you with the code, I'm not as familiar with the old-style typedef. But Wledge's code looks pretty nifty, I didn't realize you could do that sort of thing!
