In what way is it not working as expected?

Maybe you can show some relevant input and relevant output and explain how the output differs from what you expect?

Also, I notice that your indentation is very inconsistent. Consider applying a consistent way of indenting. For example, indent the complete loop body by four spaces below the while but don't indent anything else, as the while(...) { ... } statement is the only block within your program.

While indenting, you might find that some things are within the block of your loop which you did not want there.
