c++ - static const member inizialitazion in template class -

in file someclass.h

#ifndef some_class_h_ #define some_class_h_  #include <iostream> using std::cout; using std::endl;  template <class t, class p> class someclass {       public:             someclass();             void somemethod();        protected:                typedef unsigned int heapposition;               heapposition somevariable;         private:                               static const heapposition nullposition; };  template <class t, class p> const typename someclass<t,p>::heapposition someclass<t,p>::nullposition = -1;  template <class t, class p> someclass<t,p>::someclass(){}  template <class t, class p> void someclass<t,p>::somemethod() {     somevariable=nullposition;     cout<<"nullposition:"<<nullposition<<endl; }  #endif 

in file main.cpp

#include <cstdlib> #include <iostream>  #include "someclass.h" using namespace std;  int main(int argc, char *argv[]) {      someclass<int,int> someclass;      someclass.somemethod();      system("pause");     return exit_success; } 

basically have templated class static const member (nullposition). have tried inizialitazion of of class, both outside class definition , inline in

static const heapposition nullposition=-1; 

when declaring member.

however, in both cases, when reference in somemethodits values random value - i.e. has not been initialized.

i have done type of thing many other times, , have never had type of problem.

what doing wrong?

can please me? thank in advance time.

thanks, gerald celente

are sure random value? have declared nullposition unsigned, assigning -1 cause cout.operator<< (invoked in unsigned overload) print large value (4294967295 32bit int)
