Insertion-Sort Progress Bar

brazyuri86 (25)
Hi people!

I make my own insertion-sort algorithm and I put a progress bar to print in the screen the progress of sort for big numbers.

Can anyone help me to optimize my progress bar. Actually it print in the screen the progress (5% - 10% - 20% ...), but I would like to print one progressive bar like this (with actualize one unique progress bar):
[__________]
[|._________]
[|.|.________]
[|.|.|._______]

Thanks!!

You can't rewrite over text using standard console features. If you absolutely must, you can get a library like curses.

That is unless the text you want to overwrite is in a single line.

Not all consoles support \b though.
