how to initialize a static map

[Rajesh1978]

Hi I have the below class

I want to initialize the static map which takes string , string
But when I compile it is giving me an erro like constant expression is required.

class FunctionCaller{
static std::map<std::s tring,std::stri ng> functionMap;
public:
FunctionCaller( ){}

};
std::map<std::s tring,std::stri ng>FunctionCall er::functionMap["function1"] = "obj1";


please suggest
Thanks

You intialize the map by:
[code=cpp]
std::map<std::s tring,std::stri ng>FunctionCall er::functionMap ;
[/code]

Since this is a private static variable you will need to use a class method to insert objects in the map.

Remember, you can only insert pair objects.
