POreading binary files C++

Body
copied!<p><p>I would like to ask for help ... I am starting in C++ and I got this homework at school ... We got to write function <code>bool UTF8toUTF16 (const char * src, const char * dst );</code> which is supposed to read <em>src</em> file coded in UTF-8 and write it into <em>dst</em> file but in UTF-16. We also mustn't use any other libraries than in my code down...<p> So the first thing I am trying to do is that I make a file "xx.txt" and in classic Windows notepad I write there for example char 'š'. Then am trying to write a program which reads each char of this file in binary mode byte by byte (or bytes by bytes) and prints it's value... but my program doesn't work like that...<p> So I have this file 'xx.txt' where is only 'š' which has UTF-8 value 'c5 a1', UTF-16 value '0161' and Unicode value '161' and I suppose result that it will print: i = 161 (hex) or something close to this result at least...<p> Here is my code so far:</p> <pre><code>#include <stdio.h> #include <stdlib.h> #include <iomanip> #include <iostream> #include <fstream> using namespace std; int main ( void ) { char name[] = "xx.txt"; fstream F ( name, ios::in | ios::binary ); unsigned int i; while( F.read ((char *) & i, 2)) /* I dont know what size to write there - I would guess it s '2' - because I need 2 bytes for the char with hexUTF-16 code '0161', but 2 doesnt work*/ cout << "i = " << hex << i << " (hex) "; cout << endl; F.close(); system("PAUSE"); return 0;} </code></pre> <p>Thanks in advance<p> Nikolas Jíša<p></p>
