The file is created if it doesn't exist, and if it does, whatever was in it is deleted.If the call to fopen fails, perhaps because the file was open or the name contains invalid characters or an invalid path, fopen returns the value 0.A binary file is a file of any length that holds bytes with values in the range 0 to 255.These bytes have no other meaning unlike in a text file where a value of 13 means carriage return, 10 means line feed and 26 means end of file.Of these two, binary files are usually the simpler to deal with.For that reason and the fact that random access on a text file isn't something you need to do often, this tutorial is limited to binary files.It's a little onerous if you are after performance, so you might limit this to debugging.

In C, you can think about the data either as files or streams.If this fails (the file might exist and be open or read only or there could be a fault with the filename), then it returns 0.The fopen() command attempts to open the specified file.With random access, you can read or write to any part of the file or stream.With sequential access, you have to loop through the file or stream from the start like a big tape.

  2. Even if that anything involves dragging myself to a dank basement bar with moody music and seven men waiting to have micro-conversations with me. When I agreed to this speed dating thing I kind of imagined some bright river north bar with lines of tables and man upon man waiting to be micro-interrogated. But it was also kind of weird because there were also seven women and, including me, I knew five of them. Speed dating might not have been my first choice for finding a date. I mean, small talk isn’t exactly my favorite thing.
