[填空题]有以下程序:
#include <iostream>
#include <string>
using nameSpace std;
class person

int age;
Char * name;
public:
person ( int i, Char * str )

int j;
j = strlen( str ) + 1;
name = new char[ j ];
strcpy( name, str );
age = i;

~person( )

delete name;
cout<<"D";

void display( )

cout<<name<<":"<<age;


int main( )

person demo( 30,"Smith" );
demo.display( );
return 0;

则该程序的输出结果为: 【13】
