What's wrong with this code?

[Jonathan Gilligan]

Can anyone tell me why this code

#include <map>

std::map<std::string, int> foo;

int test_stl(std::string key)
{
    return foo.find(key)->second;
}

Gives me about a page of STL compilation errors in Visual Studio .NET? Can anyone give me an example of working code that uses a hash_map or a map with an std::string key type? Why couldn't Science, in the long run, serve As well as one's uncleared lunch-table or Mme X en Culottes de Matador?     James Merrill

If you actually include the compile errors (or at least the first few), then it will make it a lot easier to determine what the problem is. Dave http://www.cloudsofheaven.org

Looks like you just need to #include <string>:

#include <map>
#include <string>
std::map<std::string, int> foo;
int test_stl(std::string key){
return foo.find(key)->second;
}
