>> Why it is necessary?

Well, it shouldn't be... I tried the code separately on both GCC and minGW compilers, and both compiled well and didn't complain...

Try adding the statement using...

#include <cstdlib>
#include <iostream>
#include <fstream>

using namespace std;

int main(int argc, char *argv[]){

string line = "";
int lineLength = 0;

Could you attach a copy of the file "ip.txt", so that we can have a look at it? Further, how is the file generated, i.e, as another program's output, or written manually with a text editor?

You...

Nope, that's absolutely fine. You won't need to change the function call, even if you add more code, that is unless and until you change the functions' arguments or something... :)

Why not try this:

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
ifstream iptilvar;

Okay, before I answer your question, a few things need to be cleared. In all the code I've seen till now, <ionstream> is by far the most striking alternative to the known, and beloved <iostream>...

Okay first things first...
What exactly are you trying to achieve with this code?

Secondly, You can get rid of some of these errors:

1. 17: error: `islowerCase' undeclared (first use this...

If cin.ignore(); fails, then try clearing the input stream, before accepting input. This can be done with cin.clear();.

If all your inputs are failing, then maybe try the following:

1. Clear...

Try adding a cin.ignore(); statement before each of your inputs.

See this: http://www.cplusplus.com/reference/iostream/istream/ignore/

Incidentally, its better you don't use fflush(stdin);....

You could try this:

FILE *in;
char line[1000];
char *token;
in = fopen(argv[1],"rt+");
if ( in == NULL) exit(1);
int i=0;
// Read the first line... move the file...

> What am I doing wrong???

A lot! .... but nothing that you can't learn from, with a little bit of effort... Your struct contains 2 functions, both of which can directly access the other struct...

Did you actually go through the links I gave, and the clue I provided in my previous posts? If so, did you not understand it? and no, your code still will read your file line-by-line.

> read from...

I have no idea where you are going to put this, so I don't know what it will accomplish. If it is inside your while-loop, then, no it will not help at all. Anyway, this approach undermines the...

while (getline(iofile,line))
{
cout << line << endl;
}


Your code is on the right track. Check out the getline function's prototypes here: getline - C++ Reference...

> I have come as far as estimating fundamental matrices for the cameras.

You have mentioned in an earlier post that you know the camera's calibration. When you talk about a fundamental matrix...

Yeah, this is a good algorithm to use for the same...

An image has to be described on a 2D plane, so the z-coordinate does not come into play here. If you just want stills of your 3D simulation, maybe you should just try writing the pixel information of...

I hadn't realized that... thanks! :) ... But it does work as std::string in my IDE (Dev C++), and it (I mean, including <string.h>) does not produce any backward warnings at all...

Are you sure that this program compiles? You seem to have used string in your code, but you haven't included <string.h> at all...!

Apart from that, could you tell us what IDE/compiler you are...

Okay, lets see:

// Classes.h

#ifndef CLASSES_H_INCLUDED
#define CLASSES_H_INCLUDED

class BClass
{
/*...*/

I think that your problem here is this line here:


#include <cstdlib>
#include <iostream>
#include <main.h> // <- See this?? What is this?? Try deleting this

using namespace std;

int...

Okay, I haven't fully understood your first question, but I'll try and clear up parts of it that I have understood. Just tell us what you want to do in context of the following, or, if this isn't it,...

A tutorial is supposed to teach you methods of doing something: in this case - "How to build a singly linked list". You could have easily emulated the workings of that list and incorporated it in...

Glad it helped! :)

Of course this code wouldn't create a.dat. You are asking it to open the file, not create it with those parameters.

Try the code below:

#include <iostream>
#include <fstream>

using...

I'm sorry, but I have to agree with ArkM - there's a ton of mistakes in the provided code. Just go through it, step by step and straighten out the code.

You may also like to see this:...

Yes, I tend to agree with Narue. I would take a pot-shot and ask for you to check the closing statement of your Graph class, and make sure that it terminates with a };

Hi!

Glad it helped! :) and yes, it was the braces which was the main problem. Just remember to put braces even for the simplest of all switch(case) statements, especially if you are going to nest...

I would also like to mention that from the memory side of things, and from the program logic, you might like to use:

BOOL CALLBACK DlgProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam);...

Hi!

I compiled your program, and it compiled successfully, but I never got the GUI part of it to work. I made some modifications to your code, and now its running, but I've no idea if it will...

Could you provide us with your complete program code, so that we can compile and debug it?

Maybe you should try this:

Make the following Window Handles Global:

HWND hWndPrincipal;
HWND hWndPrincipal2;
HWND hWndPrincipal3;
HWND hWndPrincipal4;

I'm not sure if this will work, but...

I agree with iamthwee. There seems no point in that segment of code! It checks a relation: if a is equal to zero or not, if a is less than b, otherwise it relates b to 0, which is pointless.

Is...
