Confusion with homework .. infile

Will that work if i am bringing in a a name of a book ex. "Principles of Chemistry", or will i have to use a 2d array ????

this is a test

you don't have to use 2D arrays.
You can pass a number to that array and it'll give you the book title back.
What i don't understand is why you're using structs at all.
Unless of course you're planning to save more stuff in that struct.

string tempTitle;
infile.getline(tempTitle,MAXLENGTH);
If I put the infile in for a string and then assigning it into a char array it doesn't work.

I get this error

c:\documents and settings\owner\my documents\visual studio 2005\projects\hw 4\hw 4.cpp(34) : error C2664: 'std::basic_istream<_Elem,_Traits> &std::basic_istream<_Elem,_Traits>::getline(_El em *,std::streamsize)' : cannot convert parameter 1 from 'std::string' to 'char *'
with
[
_Elem=char,
_Traits=std::char_traits<char>
]

CAN YOU THINK OF SOMETHING

this is what I have so far.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
using std::cin;
using std::cout;
using std::endl;
using std::string;
using std::ifstream;
#define MAXBOOKS 9
#define MAXKEYWORDS 3
#define MAXLENGTH 50
struct Book
{
char title[MAXBOOKS];
char keyWord[MAXKEYWORDS][MAXLENGTH];
char position;
};
int fillArray()
{
char title;
char keyword1;
char keyword2;
char keyword3;
Book theBook;
ifstream infile("library.txt");
while(true)
{
for(int i = 0; i < MAXBOOKS; i++)
{
// infile >> theBook.title[i];

string tempTitle;
infile.getline(tempTitle,MAXLENGTH);
//strcpy(theBook.title[i], tempTitle);
cout << theBook.title[i];

for(int j = 0; j < MAXKEYWORDS; j++)
{

}
}
}
return 0;
}

plus a main function

This
is not a proper definition because Title has no type. It probably ought to be something like

in which case main should be

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
using std::cin;
using std::cout;
using std::endl;
using std::string;
using std::ifstream;
#define MAXBOOKS 9
#define MAXKEYWORDS 3
#define MAXLENGTH 50
struct Book
{
char title[MAXBOOKS];
char keyWord[MAXKEYWORDS][MAXLENGTH];
char position;
};
int fillArray()
{
char title;
char keyword1;
char keyword2;
char keyword3;
Book theBook;
ifstream infile("library.txt");
while(true)
{
for(int i = 0; i < MAXBOOKS; i++)
{
// infile >> theBook.title[i];

string tempTitle;
infile.getline(tempTitle,MAXLENGTH);
//strcpy(theBook.title[i], tempTitle);
cout << theBook.title[i];

for(int j = 0; j < MAXKEYWORDS; j++)
{

}
}
}
return 0;
}

This is what I have but it doesn't work can you inform me there is something wrong with me infile but I dont know what.

This is the error

getline does not work on type string, it works on array of char.

If you are going to have more than 1 book you need an array of Book structures (or a linked list but let's not complicate things) and finally you have declared you book local to FillArray so as soon as you exit the data will be gone

duh, you're incrementing the struct array, not the .title lol. I'm such an idiot.

I tried this :
and then i got the error

c:\documents and settings\owner\my documents\visual studio 2005\projects\hw 4\hw 4.cpp(33) : error C2664: 'std::basic_istream<_Elem,_Traits> &std::basic_istream<_Elem,_Traits>::getline(_El em *,std::streamsize)' : cannot convert parameter 1 from 'char' to 'char *'
with
[
_Elem=char,
_Traits=std::char_traits<char>
]

The message i am trying to bring it is "Principles of chem"

Not if you are using the structure

you aren't so I suspect you aren't doing that or you haven't change the code correctly.

Ok i got that alright and thank you, but one other thing...
The file I am wanting to bring in, is read like this...

Title
keyword
keyword
$

my problem now is how do I make the key words is a single array... Is there a way to call theBook[i].keyword[j] and have j as a inside for loop???

See this post

that I have already made to this thread.

Oh I am sorry i didn't even see it. Thank you so much.

Can I ask a question on this thread?

What if you have no idea how big the infile is? How do you set MAXBOOKS and MAXLENGTH?
