Lets imagine that 512 is only buffer size so the buffer can containt 512 or less symbols.

Infinity: Thanks very much! As a side question, what is the point in having both an eofbit and a failbit if one also sets the other?<br />

<br />
when the eofbit is set - it doesn't necessarily mean that the failbit is set too - in this specific case it's true though :<br />
<br />
&nbsp; &nbsp; eofbit is set because the end of the file is reached<br />
&nbsp; &nbsp; failbit is set because you tried to read further than the end of the file<br />
<br />
There's a slight difference in meaning ...

What happens in the following:<br />
<br />
fileInput.read(memoryBlock<wbr />, 512);<br />
fileInput.close();<br />
<br />
But from the current read position to the end of the file is only 511 bytes? Will it read 511 bytes and silently ignore the 512 byte, or should a specific check be done to ensure 512 bytes are there, and handle accordingly?<br />

Reading more than possible from a file.

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
