Even easier in C++

     #include<iostream.h>

     char buffer[132];
     ifstream is( "filename.txt");

     is.getline( buffer, sizeof(buffer));
// and incidentally
     int usedlength = is.gcount();


"getline" by default stops on and discards a linefeed.  You can change this
terminator by supplying it as a third parameter.

You can read from a null-terminated string or char array instead of a file
by replacing the declaration of "is" with
     istrstream is( array);
or from an unterminated char array with
     istrstream is( array, arraysize);
