"Implode" an Array

[Diablo84]

Does C++ have a function similar to the PHP function, implode?

For example:

$var = implode('|',$thearray);

Which would join the array values together in a string with the | character in this case, eg: item1|item2|item2|etc

I know you can use a for loop in C++ to loop through each item (or write a custom function) but i was wondering if there is an implode style function in existence.

As a side note, does c++ support associative arrays? eg: array["key"], array["anotherkey"] etc. Judging by what i have seen so far it seems that numeric keys are the only option, i'd just like to confirm this.

Thank you very much

Yes, in C++ they're called maps.

#include <map>
#include <string>
using std::map,std::string;
...

map<string, int> array;
array["one"] = 1;
array["two"] = 2;

EDIT:
And there's no 'implode' function, but it's easy to write one:

#include <sstream>
#include <string>
template <typename T>
std::string implode(char ch, std::vector<T> vec)
{
  std::stringstream out;
  for (int p=0;p<vec.length()-1;++p)
    out << vec[p] << ch;
  out << vec[vec.length()-1];
  return out.str();
}

std::map will do exactly what you're looking for.

Thank you, i hadn't expected associative arrays... or maps, to be available so that's an added bonus.
