[programmmercplusplus]

dear forum,

I have a standlone application (c++/GUI). user has the ability to create reports and name them.

there are various items grouped into different categories. I am trying to make a group of items which dont belong to anyother categories.

for example:

items list: a, b, c, d, e, f, g

group1 group 2 None( items dont belong to any group)
a, b, d a, b,f c,e,g


canyone help me with the code in c++. Please

For each "item", enumerate how many "groups" it is a member of, and if that number is zero, add it to the "none" group.

_{I REALLY hope that helps.}
