C++基础知识_class是对struct的扩展

 3 struct person
 4 {
 5     char *name;
 6     int age;
 7     char *work;
 8     void (*printInfo)(struct person *per);//函数指针
 9 };
10 
11 void printInfo(struct person *per)
12 {
13     printf("%s,%d,%s\n",per ->name,per ->age,per ->work);
14 }
15

17 int main(int argv,char **argc)
18 {
19     struct person persons[] = {{"zhangsan",10,"teacher",printInfo},{"lisi",20,"doctor",printInfo}};
20     persons[0].printInfo(&persons[0]);
21     persons[1].printInfo(&persons[1]);
