Hi! I have the following problem: I need to make a digital timer. I must have always 4 digits in the format MM:SS. I know the functions width() and fill(), but I do not know how work with them to acchieve what I need.
For example 1 minute and 2 seconds must be shown as: 01:02, and not 1:2, or 1: 2.
Any help would be appreciated.
