map<int ,std::string>

[darkkal]

Hi I'm a student majoring a computer .

I tried to make a simple hashing table like (int) 1 , (std::string) "One"
There is a problem in using std::map ㅜㅜ


this is a simple code.
PLZ~~Help me :)

#include <iostream>
#incluce <map>
 
int main()
{
 
    std::map<int ,std::string> test ;     
    test.insert(std::make_pair(1,"as"));
    test.insert(std::make_pair(2,"as"));
 
    std::map<int,std::string>::iterator start = test.begin(); 
    std::map<int,std::string>::iterator last = test.end();
    for(start ; start != last ; ++start )
    {
        std::cout << start->first ;
        std::cout << "\t"  ; 
//    std::cout << start->second <<std::endl; //it does not work 
    }
}

Thank you^^;

When you make the pair to insert, it may be treating "as" as a character array, not a string? That's the only thing I can think of.

In your for loop why do you have for(start ; . . . ) as your first parameter. You already initialized it so you don't need anything in that first field.
