I have been trying to read lines (ascii chars with backspaces) from textfile (Squid access.log) using fstream:
char log_line[255];
ifstream log_file("access.log");
while(!log_file.eof()){
log_file>>log_line;
cout<<log_line<<endl;
}
log_file.close();
But if original line from file is like "1046385006.546 2001 192.168..." , then variable log_line is "1046385006.546".
How to read full line with BACKSPACES?

That is a good improvement, but an even better solution is to use the global getline, instead of the member getline. The global getline will read a line of _any_ length and store it in a string object, like
sring log_line;
ifstream log_file("access.log");
while(!log_file.eof())
{
getline(log_file,log_line)
cout<<log_line<<endl;
}
log_file.close();
I have a similar question...
I have to read in lines from a file and parse it to extract the data.
For example I read in a line "0 11 2 5", I can do this with a "getline", but then I have to assign 0 to a variable 11 to another variable, 2 to another and 5 to another. These variables are all of data type "int".
I've tried doing a "get" instead of "getline", but that reads in one character at a time. What I need is a way to read int. Any ideas or suggestions?
Thanks,
raj

1) Don't you mean BLANKS ?
2) use getline
char buf[256]; // max line in file
logfile.getline(buf, 256);
