Re: Program to find occurences of a word in a file

all what I get is that in case of default constructing ,intrinsic
rvalues go zero.

#include <iostream>
#include <conio.h>
using namespace std;

template <typename T> struct testd{
   T t;
   testd():t(){};
};

int main(){
   testd<long> tl, *ptr=new testd<long> ; cout <<"One\n"<< tl.t << endl;
   cout <<"Two\n"<< ptr->t << endl;
   delete ptr;

   cout <<"Three\n"<< long() << endl;

   long* l=new long;
   cout <<"Four\n"<< l << endl;
   new(l)long();
   cout <<"Five\n"<< l << endl;

   delete l;

   cout<<"Six\n" << testd<long>().t <<endl;

   getch();
   return 0;
};

only the third output comes zero.
so in case the container uses placement new nop is done and it cannot
zero-default the value.
now I believe that it is the default allocator - not the ctor - who
resets the allocated bytes to zero .
