Try to the same way, as you described.. Follow your algorithm.. Take array with some random initialization with * and dot. Then by loops, traverse colomn until you find a dot, if you find then traverse row from that. If you gone trough a colomn and row then print all traversed. Otherwise go next colomn.. Give a try.. And post your try.. Then some one help you to solve it.
