Answer 1

because printf is made for c and not c++. it prints c strings which are just arrays of chars that are terminated by '\0', but string in c++ is a class and not a c string and therefore printf can‘t handle it. just use cout if you are using c++.

Answer 2

you are trying to print a string using printf, use cout or it->second.c_str()

Answer 3

but why it is not working with printf?
