验证 结构体指针与自增运算符

#include <stdio.h>
#include <stdlib.h>

int main() {

 struct student {
  char *name;
  int score;
 };

 struct student st = {"Brian", 97};
 struct student *ptr = &st;

 printf("ptr->name = %s\n", ptr->name);
 printf("*ptr->name = %c\n", *ptr->name);
 printf("*ptr->name++ = %c\n", *ptr->name++);//获取首地址字符后，将name指针友谊一位，指向r
 printf("*ptr->name = %c\n", *ptr->name);
 printf("ptr->score = %d\n", ptr->score);
 printf("ptr->score++ = %d\n", ptr->score++);
 printf("ptr->score = %d\n", ptr->score);
 return 0;
}
