Queue and Stacks

a) A C++ program that implements the Stacks ADT. b) A C++ program that implements the Queue ADT using two stacks (make use of the Stacks ADT that you have implemented in a). can anyone help me with these?

stephen, please don't help him for his homework... people asking for such too general questions and that can't do the job they've been assigned to don't deserve a good answer
I didnt see Stephen do anything bad. He just referred him to the STL, and if the guy works it out from there, I believe that is OK. Even we need pointers to references some times. Cheers, Sebastian -- Contra vim mortem non est medicamen in hortem.

yeah, i understand this point of view and i conccur somewhat. but what i also observe - sadly - is that many people (newly registered to codeproject) come there to ask for one to make one's homework :( they not only miss the point of what homeworks are beeing for (to learn and progress) but they ask their question a somewhat hurting way... i can used to newbies that don't know the site, don't know where to ask, and don't really know where to start with their assignment, but i can't used to those guys that tell you : "do this, so that, the program has to output/compute this or this datas"... hey, we're not paid to do one's job. we can only help or link someone to a possible/best way to solve a specific point. i've quoted this from Bjarne Stroustrup's FAQ yesterday : "Will you help me with my homework? No. Sorry. I don't do (other people's) homework. I get too many requests for help with homework and help with finding bugs in student programs to be able to find the time. Anyway, having a distant expert fix your programs is not the best way to learn. Try finding a local person with C++ experience that you can ask for guidance. A good mentor is the best help a student can have; maybe that's why they are not easy to find. Also, no, I will not suggest "a good project for a student to work on". My experience is that learning enough about a student and his/her course to know what level of difficulty is required and what kind of project is of interst takes time. To think of a good project is then non-trivial, and to explain exactly what the project is and how to approach it can take several messages and several hours. I just don't have that kind of time. Remember, these request come at least weekly. Finally, some students seem to have the idea that if I suggest a project, I am morally obliged to provide quite detailed help in its completion. " do you better understand why i reacted like that ?

Yes, exactly what is it that you need help with?

i hv a stack ADT program. I hv to use it to implement a queue.. considerin the FIFO and LIFO rules for both of the structures i hv no freakin idea how to put it together.... -- modified at 10:35 Thursday 6th April, 2006

Not possible, technically. A queue is a FIFO data structure whereas a stack is a LIFO data structure. Since both of these are linked lists, however, it should be easy enough to implement. Consider:
class list
{
// put things in here that are common to both data structures
};class queue : public list
{
};class stack : public list
{
};

If the homework was to "implement" a stack or queue then I didn't do it, I pointed him at existing implementations. It's all very trendy at the CodeProject to harp on about homework, and I agree that you shouldn't do a students work for him: But you don't have to put him in "solitary confinement". I just pointed the dude in the right direction (or as I said, possibly the wrong direction if the alleged assignment was to implement it yourself). Steve
