c ++中规定，struct 和class 的区别，仅仅只是，struct 里面的成员变量 的属性是Public,而 class里面的成员变量表示的是Private ，如果你都封装性没有很高的要求的话，直接替换就可以了

[Falleyes]

最简单的，不加成员函数，修改类似如下：

typedef struct 
{
  char num[10];
  int hour;
  int min;
  int sec;
  int out_hour;
  int out_min;
  int out_sec;
}Car;

class Car{
public:
  char num[10];
  int hour;
  int min;
  int sec;
  int out_hour;
  int out_min;
  int out_sec;
}

[ralln]

直接改，struct中的成员变为类成员变量，下面的函数选择相关的放入类里成为成员函数

[707wk]

简单快速 直接替换关键字，如果大改的话就新建个类，然后函数全调里面去

[幻夢之葉]

我很好奇为何要替换？！
