C++: Using a multiset?
multiset<myStruct> set1;
multiset<myStruct>::iterator it;
myStruct arr[10];
struct myStruct{
double amount;
int count;
} ;
myStruct apple;
apple.amount = 2.0;
apple.count = 1;
I can do this : arr[0] = apple;
But I can't do this: set1.insert(apple); //Won't work because I can't even compile.
Can someone spot what it is that I'm doing wrongly?
I need to use a multiset because I don't want to contain my data in a predefined structure such that of the array with size 10 or size 100.

multiset keeps the element sorted so it needs a way to compare two elements. Define an operator< for comparing two myStruct objects or pass a comparator as a template argument.
If you only try to avoid a fixed size you better use another container like vector.
