[Dev-C++] getting unexpected results

[dawood <da...@ku...>]

Can anybody let me know, why the below code is not working correctly.

#include <iostream.h>
#include <stdlib.h>

int main()
{
   struct str_misc {
     char* cstr;
   };
   str_misc str_ex[12];
   char* buf;

   cin>>buf;
   str_ex[0].cstr= buf;
   cout<<str_ex[0].cstr<<"index=0"<<'\n';

   cin>>buf;
   str_ex[1].cstr= buf;
   cout<<str_ex[1].cstr<<"index=1"<<'\n';

   cout<<str_ex[0].cstr<<" repeat index=0"<<'\n';
   cout<<str_ex[1].cstr<<" repeat index=1"<<'\n';

       system("PAUSE");
       return 0;
}
