Question

I have a code and from kladblok.txt there is a file with the following numbers:

1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10

How can i get the output :

1111111111
2222222222

etc..

Can someone help me?

Answer 1

If you just want to print it rotated 90 degrees, then just change the start/end/increment of your loops. Say you have int data[10][10] in the original rotation.

Then you want to start in the lower left and go up. Move right one space, start again at the bottom and go to the top, etc:

int i, j;

for (i = ?; i ? ?; i??)
{
    for (j = ?; j ? ?; j??)
    {
        /* print element [i][j] (or perhaps [j][i]) */
    }

    /* do a carriage return here */
}

/* What should the question marks be? */
