problem with reading in a file
Author
ok i have a file defined as so
00 00 00
01 02 01
01 01 01
now i open the file the following way
ifstream fin("data.dat");
ofstream fout("data1.txt");
What are you trying to do? Do you want to fill data1.txt with what's in data.dat? If so, then you shouldn't be using cin or cout. You should be doing:

ifstream fin("data.dat");ofstream fout("data1.txt");int a;fin >> dec;while (!fin.eof()){ fin >> a; fout << a;}fin.close();fout.close(); "Now go away or I shall taunt you a second time"

well i forgot to say that im trying to read in the data.dat file and load it into an array of 3x3 but right now im just doing testing to get my algorithm working to read it into an array and display it in my data.txt file to see if it works
[source]
ifstream fin("data.dat");
int array[3][3];
fin >> dec;
for (int i = 0; i < 3; i++)
{
for (int k = 0; k < 3; k++)
{
fin >> dec[k];
}
}
fin.close();

how does the array[3][3] fit into your code and also what does fin>>dec do when u add it before the loop?
