Confusion with homework .. infile

[jjh]

So with infile I have this so far:

#define MAXBOOKS 9
ifstream infile("library .txt");
struct Book
{
title[MAXBOOKS]
}
while(true)
{
for(int i = 0; i < MAXBOOKS; i++)
{
char tempTitle[MAXBOOKS];
infile.getline( book.title, MAXLENGTH);
}
}

I also have the main function, but my question is with the getline. My problem is how do i get the book.title to go into the title[0].
if i try to declare it by setting book.title[0] = book.title, I come up with an error obviously.. but how do i get the infile into book.title[0]????

[jjh]

I tried this :

for(int i = 0; i < MAXBOOKS; i++)
        {
 
            string tempTitle;
            infile.getline(theBook[i].title ,MAXLENGTH);
            cout << theBook[i].title;
                 }
 

and then i got the error

c:\documents and settings\owner\ my documents\visua l studio 2005\projects\h w 4\hw 4.cpp(33) : error C2664: 'std::basic_ist ream<_Elem,_Tra its> &std::basic_ist ream<_Elem,_Tra its>::getline(_ Elem *,std::streamsi ze)' : cannot convert parameter 1 from 'char' to 'char *'
with
[
_Elem=char,
_Traits=std::ch ar_traits<char>
]

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

Not if you are using the structure

struct Book
{
  char title[MAXTITLE];
  char keyWord[MAXKEYWORDS][MAXLENGTH];
  char position;
};
 
struct Book theBook[MAXBOOKS];
 

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???

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?
