I'm trying to read in a group of numbers one at a time until I reach the end of the line from the input file. Something like this:
999323892...
I thought that it was possible to do something like this:
while ( input !='\n')//where input is type char
{...
But that doesn't seem to work, no errors, just gets caught in an endless loop. I just can't seem to recall how this should be written, any help would be great.
I have attached a file with a simple example... hope that helps!
Nothing more to tell about me...
Happy day =)
Here's probably the easiest way (previous code edited to use std::getline and to make it ANSI-C++ compliant)
Now, string will contain the first line of the file (everything until the first newline) so you can do what you want with it. Your best bet is probably to read whole lines in, and then process them later.Code:#include <iostream> #include <fstream> #include <string> int main(){ std::ifstream file("test.txt"); if( file == NULL){ std::cerr << "Error opening file << std::endl"; return 1; } std::string line; std::getline(file, line); }
