sort with vector<struct>

[Oliver Block]

Hi,

can anyone if it is enough to place the elements of a structure in a
different order when you want to sort it.

for example sort by name:

struct item 1 {
String name;
int age;
}

or otherwise sort by age:

struct item 2 {
int age;
String name;
}

I never used that routine. Would that work and are there better ways?

bye,

Oliver

You need to write a predicate "less" that compares the struct according
to your requirement. Google around - there are lots of examples.

thank you! I added a class cmp which implements just Operator().
