More specifically, this is your problem (the one in bold):
bookinfo(int&, char [51], char [14], char [31], char [31], char [11], int&, double&, double&)

Try changing it to just int, as int& is...

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

>> Why do we need to add 1 to lineLength?

That's because when we declare an array, say int arr[5];, we are allocating, effectively 5*2 = 10 bytes of memory for it. Now, in your program, lineLength...

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

using namespace std;

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

string line = "";
int lineLength = 0;

Then use both the constructors in the program :), like:

struct real
{
/*...*/
real(const double val);
real(double val, double err);
/* ... other constructors ... */
};

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...

Which version of minGW are you using? I've tried the code on both my minGW and GCC Compilers, and they don't come up with any sort of error...

To the best of my knowledge(which might be bad), this...

I'm afraid I'm a bit confused by what you want to do... This is my understanding of your question:

1. You'd like to initialize objects of real using this syntax: real x = 1.;, where error is...

Okay, then how about:

#include <iostream>

using namespace std;

struct real
{
double value;
double error;

I'm not sure, but try:

real x = {1.};

With this, you wouldn't need to overload any operator...

Hope it helped!

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;

Agreed :) I wasn't defending the practice, but I was merely substantiating that it wasn't the problem juniper2009 was facing in the code provided...

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>...

I'm glad it helped! :)

I'm still not very sure what you want isLowerCase for, and how it should be used in your program, but, here's how I understand your program:
1. Load the 10 characters into ...

Or you could just break out of the loop, using the break; statement; so that it'll stay open long enough for you to see that you've won... :)

First of all, I would highly recommend you go through this (http://www.cplusplus.com/doc/tutorial/) tutorial, that'll help you brush up some basics in C++, before starting to make your own programs....

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.

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;

I'm not sure whether this is what you are looking for, but try this:
