Thread: istream::getline()

I'm going by a fairly old book here (I'm not particulary bothered, it's a great book), so that might be my problem, but does istream::getline() still exist? My compiler gives me an error when I tell it:

Code:

const int bsz = 30;
char* buf[bsz];
ifstream("test.txt");
initin.getline(buf, bsz);

"Could not find match for istream::getline(char * *, const int) in function main(int, char * *)"

Any help?
EDIT I think this may be because all my calls to getline() are inside while(strstr(etc.)) which the compiler is also telling me are erronous. Exact code:

Code:

const int bsz = 30;
char* buf[bsz];  //hold curr line
while(!strstr(buf,"<style"))
  initin.getline(buf, bsz);

initin being: ifstream initin(argv[1]);
Giving: "Could not find a match for 'strstr(char * *, const int)' in function main(int, char * *)".

Thats because you have created a pointer to an array of chars. You need a pointer which points to a char, ie. char *Buf;
If you change your code to char buf[bsz], that should work.

sorry jlou - at the time i wrote the reply no one had written a response.

I use this function in the following manner:

Code:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main()
{
   ifstream file;
   file.open("myfile");
   string buffer;
   getline( file , buffer );
   cout << buffer << endl;
   return 0;
}

Compiled in Dev CPP. Just switching the parameters!
Hope that helped!
