第3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;
