Dear there, in my .cpp file, the compiler complains there is a syntax error for the last line? what's the error? thanks.
Code:#include <iostream> #include <iomanip> #include <sstream> #include <fstream> #include <string> #include <vector> #include <deque> #include <cassert> #include <cstddef> #include "commonio.hpp" #include <map> #define P(x) cout << #x << " : " << x << endl; using namespace std; typedef map<string, time_t> Prodrange; Prodrange pstart, pend; pstart["AUD_CAD"]=1191171604;
What error does it say? There could be a number of things wrong with this snippet.

You can't have anything but declarations outside of functions.
I might be wrong.
Quoted more than 1000 times (I hope).Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
hey, thanks for reply. all I want is a global look-up table, mapping string to time_t. For the code I attached, what I want is to be able to use
wherever I need a time_t value.Code:pstart["USD_CAD"]
Is there a good way to do it? Thanks.
You could set the values at the beginning of main. You could create a function that returns a map initialized with the data and initialize the map before main.
Boost.Assign also has nice things for initializing containers, e.g:Code:map<std::string, int> globals = function_filling_map();
Code:#include <boost/assign.hpp> std::map<std::string, int> globals = boost::assign::map_list_of ("Hello", 1) ("world", 2) ("!", 3);
I might be wrong.

I played a while trying the techniques suggested, it worked out. I further tried to use singleton to setup global variables. Eventually I said to myself, these are constants, not variables, so I fell back to the old and good enum. Thanks for the suggestions.
