Thread: simple map<string,float> not working

Code:

#include <iostream>
#include <map>
using namespace std;

int main()
{
	map<string, float> name_weight;

	name_weight["manav"] = 62.5f;
	name_weight["khushi"] = 67.5f;

	for(map<string, float>::iterator it = name_weight.begin(); it != name_weight.end(); ++it)
	{
		cout << it->first << " weighs " << it->second << "Kg" << endl;
	}

	return 0;
}

This simple map example gives me the following error under MSVS .Net 2003:
test4.cpp(14) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const std::string' (or there is no acceptable conversion)

Add this:

Code:

#include <string>

Thanks!
I think I am depending too much on compilers error reporting!
