Thanks,  this should be correct ?

//
// Display map properties
//
template<class T, class A>
void ShowMap(const map<T, A>& v)
{
 
  typename  map<T, A>::const_iterator  ci;

       
    for ( ci = v.begin();  ci != v.end();  ++ci)
        cout << ci->first << ": " << ci->second << "\n";

    cout << endl;
}



instead of   incorrect :

template<class T, class A>
> void ShowMap(const map<T, A>& v)
> {
>   for (map<T, A>::const_iterator ci = v.begin();  //  line  107

if this is correct then I have inderstood it,

 'typename'  was greek to me
