How to read and write binary file using readfile and writefile ?

Code:

int main()
{
    int variable[]={10000};
    int var[1];
    DWORD dwBytesWritten = 0,dwBytesRead=0;
HANDLE file =    CreateFileA("c:\\friendzia.dat",0x10000000 ,3,0,2,0x80,0);
WriteFile(file,variable,4,&dwBytesWritten,NULL);
ReadFile(file,var,4,&dwBytesRead,0);
cout<<var[0];
CloseHandle(file);
getch();
return 0;
}

Please correct my mistake.

Firstly, it's idiotic not to use the symbolic names for the flag parameters to CreateFile.

Secondly, you either have to reposition the file pointer or close/reopen the file to read the value you just wrote.

Try

Code:

SetFilePointer(file, 0, NULL, FILE_BEGIN);

between your write and your read.

Yes, I figured that out, Now I just want to read a binary file and print it to console 4 byte at time .
kindly help
