C++ newbie: how to cout 2D array to screen all at once, not row-by-row?

[Antst]

Hi everyone:

I have what is probably a dumb question about using cout to display a 2-D array on screen.

I want my code (below) to output an array to the screen once. But instead, it is outputting it row-by row. The entire array is shown after many unfinished arrays are shown.

I would appreciate it a lot if someone could tell me how to suppress all the intermediate/unfinished arrays so that only the finished array appears. Thanks a lot.

for (int i = 0; i < rows; i++)
{
for (int j = 0; j < cols; j++)
{
cout << setiosflags(ios::showpoint | ios::fixed | ios::right)
<< setprecision(4)
<< setw(12)
<< m[j];
}
cout << endl;
}
Hi Cubbi--thanks for your help. Sorry I was unclear. What I mean is that I would like ONLY my finished matrix to appear on the screen.

Right now what is happening is that the matrix appears repeatedly--with a new row filled in each time it appears.

So instead of something like:

[1][2][3]
[4][5][6]
[7][8][9]

I get:
[1][2][3]
[0][0][0]
[0][0][0]

then:
[1][2][3]
[4][5][6]
[0][0][0]

then:
[1][2][3]
[4][5][6]
[7][8][9]

Is there a way to suppress the intermediate steps? I have a LOT of output and it would be great to only have to deal with the finished product. Thanks!

Here is the code showing how to print 2d array.....

for(int i= 0; i < 20; i++)
{
for (int j = 0; j < 10; j++)
{
cout<<"%d %d ", a[j];
}
}
