creating array in c++ with string index

I am wondering if it is possible to create an array whose index are string.

For example I want to create a 2 dimensional array which looks like this:

array["first"]["second"]=8;

then I want to make a loop to verify each elements of my array.

In PHP we have foreach, but I couldn't find the equivalent command in c++.

Arrays are Evil!

what you want is a std::map<std::string, std::map<std::string, int> > (not the space in between the last two angle brackets, it is required).

there is a for_each in the STL <functional> header. It's a bit complicated by itself, but with boost::lambda and/or boost::bind it's a win.

I am not quite sure, but i think it can be done with enum in JAVA. I think C++ has the same option. try enum

The enum keyword is used in C++ to create enumerated constants. STL maps are the way to go on this one.
