create and write to file (basic question)

[carpeliam]

How do you create and write to a file?

(I know, it's a basic question, but I'm a Java programmer who doesn't know C++ so well.) Liam Morley

#include<fstream>
using namespace std;
int main()
{
ofstream x;
x.open(&quot;xxx.txt&quot;
x<<&quot;hello&quot;;
x.close();
return o;

There are two other posibilities:

1.Using MFC support:


CFile file;
CFileException e;
char* pFileName = &quot;test.txt&quot;;
if( !f.Open( pFileName, CFile::modeCreate | CFile::modeWrite, &e ) )
{
TRACE0(&quot;File could not be opened&quot;
TRACE0(&quot;Exception: &quot; + e.m_cause);
}
2.Using SDK functions:

LPSTR lpszMessage = &quot;Sample&quot;;
BOOL fResult;
HANDLE hFile;
DWORD cbWritten;

hFile = CreateFile (TEXT(&quot;\\MYFILE.TXT&quot,// Open
GENERIC_READ, // for reading
FILE_SHARE_READ, // Shared
NULL, // No security
CREATE_ALWAYS, // Existing file only
FILE_ATTRIBUTE_NORMAL, // Normal file
NULL); //No template

if (hFile == INVALID_HANDLE_VALUE)
{
// Your handling code goes here.
return;
}
fResult = WriteFile(hFile, lpszMessage,
(DWORD) lstrlen(lpszMessage) + 1, // include terminating null
&cbWritten,
(LPOVERLAPPED) NULL);
CloseHandle(hFile);

Hope this helps you,s-)
