Hey guys,

I'm about to start on a research project about multi-threading. I'm very comfortable with c++ oop/data structures concepts, but am completely new to programming with multiple threads. ...

click me (http://www.daniweb.com/forums/announcement8-2.html)

Sorry for the confusion. Let me try to clarify it a little. What I'm trying to do is to get two already written programs to work together. I have one program that gets data from a Laser Measurement...

So let me see if I understand this. If I use

template <class T>
std::string to_string(T t, std::ios_base & (*f)(std::ios_base&))
{
std::ostringstream oss;
oss << f << t;
return...

I am trying to convert an array of longs to an array of chars. There are 1081 elements in the long array. Each element is 4 digits long. Is there a function in C++ that will convert a long something...

So my Data Structures class has finished the book we were using, but we still have a week of school left. My instructor has started going over binary files... only problem is I wasn't there when he...

Awesome. The bot is currently Windows based, but we have plans on migrating to Kubuntu eventually... hopefully next year.

Thanks again.

I'm going to be working on a summer research project with my college's robotics team. My task is going to be to develop a program to communicate with the robot via 802.11g.

I would really like to...

Ah, nice. I'll give that a try. Thanks!

I know the problem sounds a little (understatement maybe) odd.
I understand what you're saying nucleon, and that would seem a lot more logical. However, I'm sure I haven't misunderstood the...

Oooh I like that one, That sounds fun.

Best C++ book I've ever used: C++ Programming: From problem analysis to problem design... by Malik.

Latest Edition...

One of my favorite projects I worked on was a small RPG type game.

I can't remember it all, but I had classes that were derived from base classes.. these were the fighters. Elvaan, Hume, etc. ...

hahah, no kidding.

This is, I guess, considered to be a programming challenge from my professor. The only thing I could think of would be to add a exception-handling block for when two ^ are...

You're right about the input. However, the input has to stay as ^ ^ 2 3 4. I need a special case maybe, to take care of the double ^?

Hey everyone,

I'm trying to make it so that my ^ operator is right justified within this binary expression tree.

For example, 2^3^4 should be evaluated as 2^(3^4). So I should get 2^81,...

I found my problem. My map() function assumes a letter is being given, and maps it to an array[0-51]. When initializing my objects to have less than that, my dynamic memory was getting buggered...

It seems the problem might be something different, for now anyways. I ran the debugger and found that the program was crashing before it ever got to the Union() function.

If you look at my driver...

Hey everyone,

I'm trying to work with Sets. I have a function Union that takes a class type Set as it's parameter. The function returns the union of class A and B.

Here is my code:
Set...

Awesomes. Thanks!

Hey guys,

Can anyone tell me why this doesn't work in VS2008? I've commented out the #includes and whatnot so you can paste it into a single .cpp file and run it.

Here are my errors:


And...

Have you tried it? If so, did you receive any errors?

Might have something to do with the fact I was running it off of my flash drive. I'll give it a whirl again tomorrow.

Thanks for the help

Hm, now I'm getting LINK errors:

Here's all of my code, to avoid further confusion. My apologies.

#pragma once
#include <iostream>
using namespace std ;

typedef char ItemType;
struct NodeType
{
ItemType info ;

Oops. Here are my errors (same in both spots):

Hey guys,
I'm getting an error at lines #9 and #14. Could someone tell me what I'm doing wrong?

StackType::StackType(const StackType & st) // copy c-tor
{
if ( st.topPtr == NULL )
topPtr...

Well, crap. Now I get this:


Here is my updated copy c-tor:


QueType::QueType (QueType const& other) //copy c-tor
{
ItemType * tmp = new ItemType[other.size] ;
size = other.size ;

Ok here's my latest code (using the non-recursive version). And I'm stuck.

#pragma once

#include <iostream>
using namespace std;

class FullQueue
{};

I get the same error when I'm not using recursion. Here's my non-recursive version:


bool Identical(QueType que1, QueType que2)
{
bool iden = true ;
if (que1.GetLen() == que2.GetLen())
{...

Ok, here's my code thus far:


// Test driver
#include "QueType.h"

bool Identical(QueType que1, QueType que2) ;
// Function: Determines if two queues are identical.
// Pre: que1 and que2...

have you tried
system("pause") ; ?

can you post your updated code so that I know we're on the same page?

No problem :)
1) Make sure the while loop is around the entire program... ending right before return 0 ; This way you can do "Try again? (y/n): " and you can change the if statement to if (letter...

You could change your while condition to while(done) instead of while(!done)... however you then have the problem of when the user gets to the end of the program, it doesn't re-execute the...

\\mistake

I see a couple of things right off, but I haven't had time to get through the whole program.

1) You're not exiting your while loop until they select Done. Your condition is while(!done).

2) ...

What type of "really odd things"?

I don't understand. How do I set data to tmp?

Thanks guys.
I realize I could do without recursion, but it was (for once) the first solution that came to mind.. so I thought what the heck, lets try it.

I'll fix the errors you've noted,...
