向各位高手请教iostream的格式问题，谢谢！

[tjsniper3]

请问，在.net中iostream的cout与cin与6.0相比，在格式上有了什么变化？请受累把cout与cin的格式写下来，最好能带中文注解。除此之外，还有哪些常用的请句与6.0不一样，请各位高手帮帮了，谢谢！

Example
// iostream_cerr.cpp
// compile with: /EHsc
// By default, cerr and clog are the same as cout
#include <iostream>
#include <fstream>

using namespace std;

void TestWide( )
{
int i = 0;
wcout << L"Enter a number: ";
wcin >> i;
wcerr << L"test for wcerr" << endl;
wclog << L"test for wclog" << endl;
}

int main( )
{
int i = 0;
cout << "Enter a number: ";
cin >> i;
cerr << "test for cerr" << endl;
clog << "test for clog" << endl;
TestWide( );
}
Input

Sample Output
Enter a number: 3
test for cerr
test for clog
Enter a number: 1
test for wcerr
test for wclog
