help with fstream write function.

[ramako]

Hi,

I am having trouble as to understanding how the write function works.

Here is my code:

	    ofstream fo(file, ios::out | ios::binary);
	    fo.write(reinterpret_cast<char *>(&vector),sizeof(int));

And vector is

vector= new int [numero];
	for (int i=0; i<numero; i++){
	 vector[i]=i;

It does open the file, but with garbage inside. I have researched about this function but couldn't find a proper explanation on how to make it work.

Your reinterpret_cast is casting an int** to a char*. Remove the & sign and it will work correctly.

Yeah, it works now! Thanks!

Does it copy ALL the vector or just the first position?
