C++完美演绎 经典算法 如 /* 头文件：my_Include.h */ #include <stdio.h> /* 展开C语言的内建函数指令 */ #define PI 3.141

/*范例14-29*/
#include <iostream.h>
class person
{
  private:
    char blood;
  public:
    char *name;
    int height;
    int weight;
    void setblood(char Vsetblood)//设定血型
    {
      blood = Vsetblood;
    }
    char getblood() const       //得到血型，设定常数成员函数
    {
      return blood;
    }
};
void main()
{
  person chang_three;
  chang_three.name = "张三";
  chang_three.height = 160;
  chang_three.weight = 45;
  chang_three.setblood ('B');
  person ja_small_ha;
  ja_small_ha.name = "江小华";
  ja_small_ha.height = 180;
  ja_small_ha.weight = 70;
  ja_small_ha.setblood ('O');
  cout<<"姓名是  "<<chang_three.name<<endl;
  cout<<"身高是  "<<chang_three.height<<endl;
  cout<<"体重是  "<<chang_three.weight<<endl;
  cout<<"血型是  "<<chang_three.getblood()<<endl;
  cout<<"===================================\n";
  cout<<"姓名是  "<<ja_small_ha.name<<endl;
  cout<<"身高是  "<<ja_small_ha.height<<endl;
  cout<<"体重是  "<<ja_small_ha.weight<<endl;
  cout<<"血型是  "<<ja_small_ha.getblood()<<endl;
  getchar();
}

执行结果：
姓名是  张三
身高是  160
体重是  45
血型是  B
======================
姓名是  江小华
身高是  180
体重是  70
血型是  O
