Hello guys,

I ve been searching for a long time for an algorithm (in c++) that would take the number of digits and give all the possible combinations between 0 and 1. For example for number of digits 3 will give

100

010

001

110

101

011

111

The funny thing is, that i think it is simple and well used BUT i cannot find it for days now. Please if anyone could help me in this i would appreciate.

Have a nice day!

Dimitris
