The error says

no matching function for calll to 'ifstream::getline (string &,int &,ch &amp'

Thanx,

INFILE.getline(line,MAXCHARACTERS,'\n'); //search each line until you reach MAXCHARACTERS or reach a newline.

It seems to not like that line. I would check documentation on the getline function, and see exactly what params it needs.

[Blaqb0x]

My book says this is the form.

(requires fstream.h header)

getline(string var, int n, '\n') - Extract characters from the input stream until either n-1 characters are read or a newline is encountered (terminates input w/ a '\0')


I declared line

string line;

ive also tried

char line[50]; //just to be sure

still no go .

I think Im decaring it wrong some how??? What's another way???

thanx

Using char[50] worked for me.

BTW: Why are you including both <string.h> and <string>? Is this program C or C++?
If it's C++ you should include the new style headers without the .h and use std:: or 'using namespace std' for short examples.

T.

(which book by the way?)

[Blaqb0x]

Hmm.
Im using anjuta to compile and build. could that make a differenence?

Yea I added that after getting desperate.

let me try this again....

Book doesn't always match the actual headers. Especially if you are reading a C++ book geared towards Win32.

istream::getline takes a char string, not a C++ string!!!!

If you want to do a getline on a C++ string, there's a different getline:

istream & getline(istream & in, string & s, char delimiter='\n'); //prototype

//usage
getline(INFILE, line);
