Ask yourself, "what is the key?" and "what is the data?".

one string is a key other are the date

Don't top post. Replies go after whatever you're responding to.

A map (or multimap) key and data must be *types*. The key can be a
string, but the data cannot be "a string, an int, and an iterator"
because that is three types, not a single type. Probably the
appropriate thing to do is define a class or structure to hold those
three quantities and make that class or structure the data type.

struct BunchOfTypes
{
string s;
int i;
multimap<string,BunchOfTypes>::iterator iter;
};
