Can print the values of iterators using printf() but not cout<<

[zan nabil]

string s ="nabil" ;
cout<<s.begin()<<nln; //gives me error

//but this prints some values
printf("%d  %d",s.begin(),s.end());

Didn't get why?

Both are wrong. With cout you have the advantage the the compiler is able to check for correctness while in the printf case it can't check.
