Multiplication Table in UNIX
How can I produce this kind of output?
Enter a number: 3
MULTIPLICATION TABLE:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
When you enter a number, it should show you the corresponding multiplication table. Plus we need to use for loops that I do not actually know. Thanks in advance! Here is my code
#!/bin/bash
echo Enter a number:
read num
iter=1
while [ $num –le 5 ]
do
res=`expr $num \* $iter`
echo $num “*” $iter “=” $res
iter=`expr $iter + 1`
done

METHODS
integer = $selection->count_selected_rows

$selection->set_mode ($type)
o $type (Gtk2::SelectionMode)

o $iter (Gtk2::TreeIter)
$selection->select_path ($path)
o $path (Gtk2::TreePath)

o $start_path (Gtk2::TreePath)
o $end_path (Gtk2::TreePath)
$selection->selected_foreach ($func, $data=undef)
o $func (subroutine)
o $data (scalar)
Call $func on every selected row in $selection's view.
iter = $tree_selection->get_selected
(model, iter) = $tree_selection->get_selected
Since most of the time you are only interested in the iter, "get_selected" returns only the iter in scalar context.
@paths = $selection->get_selected_rows
Returns the Gtk2::TreePath of each selected row, or an empty list if no rows are selected. The model is not returned, as documented in the
C API reference. To get the model, try "$selection->get_tree_view->get_model".
treeview = $selection->get_tree_view
$selection->unselect_all
$selection->unselect_iter ($iter)
o $iter (Gtk2::TreeIter)
$selection->unselect_path ($path)
o $path (Gtk2::TreePath)
$selection->unselect_range ($start_path, $end_path)
o $start_path (Gtk2::TreePath)
o $end_path (Gtk2::TreePath)
Since: gtk+ 2.2
