writing to binary files....

how do i write to a binary file without it thinking that I'm writing it as a normal file?

ofstream savefile;

savefile.open("DEFAULT.B3D",ios::out | ios::binary | ios::trunc);

for(int a=0;a<30;a++)
{
for(int b=0;b<30;b++)
{
savefile <<'a';
}
}
savefile.close();

that doesn't seem to work, i think it might be that I'm trying to use the <<, but is there another way to output to the file? (i'm trying to output a matrix to the file, but I used an a to see if it even worked......

savefile << level[a] [b];

use the member fucntions read and write instead of operator>> and operator<<

savefile.write(level[a] [b],2);

ok, i replaced it with that, but it only takes const char *, and I'm trying to write a float value....................and wtf is the second parameter for? lol

savefile.write(reinterpret_cast< const char* >( &level[a][b] ), sizeof( **level ) );

or, rather than looping, you can simply do

savefile.write(reinterpret_cast< const char* >( level ), sizeof( level ) );
