C++ program get terminated -

i need know why program terminated when ever compile it. cant understand reasons behind termination. please tell me problem solutions. thanks.

#include<iostream.h> class citizen{   private:           char* name;           char* nationality;   public:           citizen(){                    name = "no name given";                    nationality = "no nationality given\n";          }          citizen(char* name, char* nationality){             this->name = name;             this->nationality = nationality;          }           void display(){               cout << "name: " << name << endl;               cout << "nationality: " << nationality << endl;          }           ~citizen(){              if(name){                       cout << endl << "\ngoing delete: "<< name << endl;                       delete []name;              }              if(nationality){                       delete []nationality;                       cout << "going nationality: "<< nationality << endl;              }           }           citizen(const citizen &obj){                        int size = sizeof(obj.name);                        name = new char[size+1];                        strcpy(name, obj.name);                         int size2 = sizeof(obj.nationality);                        nationality  = new char[size2 + 1];                        strcpy(nationality, obj.nationality);                        cout << "\ni'm copy construcotr\n";           } }; 

the reason termination first line, should be

#include <iostream> 

(note: no .h). old header iostream.h deprecated (actually never officially part of c++).

some more error pop up, using char* instead of const char*, ask when need fix them.
