I can figure it out why my compiler response like this when i try to access ->first and ->second fields of iterator. I used before a map structure but not with a string as key.
ERROR: error C2675: unary '++' : 'std::string' does not define this operator or a conversion to a type acceptable to the predefined operator
#include <iostream>
#include <map>
#include <string>
using namespace std;
void display(map <string, string> v){
map <string, string> ::iterator it = v.begin();
map <string, string> ::iterator end = v.end();
for (; it != end; ++it){
cout << "Name:" << it->first << "---->";
cout << "Adress:" << it->second << endl;
}
}
int main()
{
map <string, string > v;
string name;
string adress;
do
{
cout << "Name:";
cin >> name; // getline(cin, name);
cout << "\nAdress:";
cin >> adress; // getline(cin, adress);
v.insert(name, adress);
} while (name == "exit");
display(v);
}
Can you tell me guys what am I writing wrong?
