Someone just post me up the code to read in data from a file.

the file is like this:

24 234.32

i need to set the int to a variable and the double to another, i cant find very many places to do this.. they all use get.line etc.

Think i am made of fail

anyways HALP ME 4chan

chomp(my ($int, $double) = `cat file.txt`);

use stringstreams.

>>2
Invalid, $int and $double aren't int and double



tmp = file('a', 'r').readline().rstrip().split()

int, double = int(tmp[0]), float(tmp[1])

>>4
If it looks like a duck and quacks like a duck, it must be a duck.

>>2 fails because he just puts a string into $int, and nothing into double.



open my $file, "file.txt";

my ($int, $double) = split " ", <$file>;

#include <fstream>

#include <iostream>



int main( ) {

   using namespace std;



   ifstream file("data.txt");

   streambuf *pbuf;

   int foo;

   double bar;



   try {

      pbuf = file.rdbuf();

      cin.rdbuf(pbuf);

      cin >> foo >> bar;

      cout << foo << ' ' << bar << endl;



      file.close();

   }

   catch( ... ) {

      cerr << "We're fucked... quitting... " << endl;

   }



   return 0;

}

$ ./a
