map<string,string> error
 

I need help with inserting a string for both key and value to a map.

while(!myHuffFile.eof()){

                string word, code;

                int freq;

                myHuffFile >> word >> freq >> code;

                if(word == ""){

                        break;

                }else{

                        _fileMap.insert(pair<string,string>(word,code));

                        _freqMap.insert(pair<string,int>(word,freq));

                }

        }

error:

error: conversion from `std::_Rb_tree_iterator<std::pair<const std::string, std::string> >' to non-scalar type `std::_Rb_tree_iterator<std::pair<const std::string, int> >' requested

can you please help me with this.

thanks

Re: map<string,string> error
 

As written there is nothing wrong with this (except I think that you would benefit from a typedef. e.g.

typedef std::map<std::string,int> mTYPE;

mTYPE aMap;

//....

aMap.insert(mTYPE::value_type(word,i));

However, I would guess that you have swapped the declarations of fileMap and freqMap.

It that is not the problem, please make a short test program and post that.

Re: map<string,string> error
 

there are two maps.
_fileMap<string,string> and the other is _freqMap<string, int>

_freqMap works fine but _fileMap doesn't. I don't think typedef will work here. I'll try it though.

i figured it out! thanks!
