The following code prints all environment variables among other things..

Can someone please elaborate to me why that is?


#include <iostream>
using namespace std;

string * GetArray()
{
string asdf[3] = { "aaaaaaaa", "aaaaaaaa", "aaaaaaaa" };
return(asdf);
}

void foo(string array[], int size)
{
// for (int i = size; i >= 0; i--) /* for a different exception */
cout << array[1] << endl;
}

int main()
{
string * array = GetArray();
foo(array, 2); // <-- required for error

return(0);
}

It's full of errors and won't compile. Besides, you're returning the address of a local variable. When you get out of the function, we're not sure what the pointer is pointing to. if I were you, I'd disassemble it and look at the value dereferenced by the pointer after the function call completes. Maybe it's a list of environment variables?
