You know of a C++ book that goes over that stuff in detail?




I prefer Brad Jones' "Teach yourself C++ in 24 days".... In my opinion it covers material better than any other C++ book I've...

I think it depends on the type of application. Java is similar to C++ in style, but you'll notice a speed difference on desktop apps right quick ;) I'd recommend going for .NET unless you're doing...

Bjarne's book 'The C++ Programming Language". It has PLENTY of tough exercises at the end of each chapter. Some of them aren't exactly easy.

Passing arrays is always a pain. I like how Dave just kept it in the public member section... Works out easier that way.

I thought about dropping to the command line and using JEdit.

I use Dev-C++ which does well with compiling, but I don't like the indentation mechanism of it. It doesn't properly align everything like it should...

I would use a map, definately. Create the map and then when you go to insert something, it would be like this:

map.insert( make_pair("Dog","Big fury animal") );

That's how I would do it, but...

#include <windows.h>

Beep(int, int);

There's no relation. You can make about any object simulate a simple physics vector, but a C++ vector is just a container. If the name was different would you still think there's a relationship?

If you already know the syntax then do something mathematical that requires some thought and time to make. For instance: Maybe something simple to compute derivatives or an equation parser. A...

Wow. Your stupidity becomes more prevalent with each post. I know you're still pissed about me letting you know how stupid your other post is, but that's not reason to carry over into someone...

You haven't even got the user input.

set up variables properly:

int k = 0;
int n = 0;


prompt the user:

I can see how you might have one class and one 'driver' program, but I don't understand why you would want more than one class.

You could create, of course, a roman numeral class:


class...

Not that it's important or anything, but you can initialize all the elements to a specific value:

vector< vector< double > > matrix( row, vector<double>(row, int_val));

It was actually my first choice to use strings. I would MUCH rather use them over char arrays, but all in all it was good practice, I guess. The reason I used char arrays is because it's the only...

No, this was a different problem. I'm using an older version of bloodshed and it as some really weird lock on files, so once I switched over it worked fine.

I have a program that reads from a file, but for some reason it never reaches the end of the file or something, because the loop never ends. I put only 2 lines of text in the file, and a loop like...

Don't worry yourself about creating the spaces and aligning into a triangle.... Thanks to C++ you can set the width and fill character of the output ;)

Alright, it worked. Thanks for all the help guys.

PS: Why would a compiler have problems with a double like that?

Yeah, I'm downloaded the very latest version right now. I'll let you know how it goes.

I'm using an older version of Bloodshed. I guess that could be the problem...... But if it works, then I will be extremememememmeemlllllyyyyyy happy.

cout << "determinant = " << determinant;

;)

This is my double:

double determinant = 2.8*5*-9.5;


It should print out -133, right?

It prints out some weird junk like: 1.8e + 04

That's pretty sweet. I guess mine was blown way out of proportion.

This is my try at it. It may not be very good, but it works.


#include <iostream>
#include <algorithm>
#include <string>
#include <set>
using std::cout;
using std::endl;

Why not use a Set and specify the string size as a sorting criterion? That way, when you want to find the longest or shortest string it would be a one liner.

Here's your problem:

cust.check_type(type,balance);

You're calling that method on a vector?

Try:

cout << "\\" << (an expression) << "\\";

\ is an escape sequence, so you must treat it with extra care.

If you're working with strings this might work (not tested), but it looks like dragons solution is probably what your looking for.


bool find_string(ifstream& file, const string& search)
{
...

So what's your question? I see nothing but a bunch of code in need of a few band aids, but no question.

Multiple opinions are always good.

If I remember right, the vector class is very slow when inserting elements to the front, or any place except the back. So, if there is a method push_front() then you probably shouldn't use it.

I'd say no, but there's no way to tell. The best thing to do is ask your teacher/professor. You can always do both and that way you won't have to worry.

You could simply loop through I guess:

bool anyNegatives(int nums[], int size)
{
for (int i=0; i<size; ++i)
{
if (nums[i] < 0)
{
return true;
}

Oh, I see. I appreciate the help sunny.

Well, I knew that would work, but I'm trying to split functionality up as much as I can. Is there not a way to have this Store class as an external source code and import it into the Person class?...

I have a class Person and a Class Store. I didn't find any way to really inherit Store in class Person, so I created Class Store in a namespace called StoreClass.

In the person class this...

Ok, I think I got it. Correct me if I'm wrong:

The first parameter(ostream&) is actually on the right side of the operator << and the object it's operating on is on the right side of the <<...

Thanks guys, that really helped a lot and cleared things up. It turned out that I didn't declare it as a friend. Now, one thing I don't understand is where the ostream& is passed since it's the...

I have the following code:
