how to orgnanize structure in a c++ program.
map of a {string–> pointing to a set of integer } and traverse all the string and element of set
A dumb and obvious solution:
// be careful about > > , single space between this two bracket
std::map<string, std::set<int> > strToIntSet;
// declare an iterator
std::map<string, std::set<int> >::iterator it;
for (it=strToIntSet.begin(); it!=strToIntSet().end(); it++){
std::cout<<it->first<<” : “;
std::set<int>::iteator it1;
// Now print out each element of set
for (it1=it->second.begin(); it1!=it->second.end(); it1++){
std::cout<<*it;
}
std::cout<<std::endl;
}
Assuming
Pretty simple.
