error that i cant quite understand,leave alone debug

[eternalLearner]

i am using

vector< pair<string,double> > v;
 
string k = function_coded(v);
 
where ,
 
string function_coded(vector< pair<string,double> > v )
{
 //do something 
}
 

but while complilling i get the following error,please help .

error: conversion from ‘std::vector<std::pair<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, double>, std::allocator<std::pair<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, double> > >’ to non-scalar type ‘std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >’ requested

i never used vector <pair ....>
does that even work...????????????????????????

tell me

hsn vector< pair< ... > > should be fine.

eternalLearner, the code you have posted compiles fine for me without errors (VS 2005). I suggest that either you have not posted what is actually in your code or you have posted the wrong piece.

Yes it does. The pair<> is an STL cointainer that has two public data members named first and second. Pair objects are used by other containers, like map, where the key is first and the value for the key is second.

Hmm,i did not post the incorrect code,but the peoblem got solved wen i declared the function_coded(vect...) in the header file as extern,though i dont quite understand why it was so .

Thanks you to all. :)
