c 用指针操作结构体数组

重点：指针自加，指向下一个结构体数组单元

 #include <stdio.h>
 #include <stdlib.h>
 #include <string.h>
 #define max 10
 #define min 3

 typedef struct Stu{
     char    * name;
     int     age;
     int   score;
 } Stu;

 //输入
 void input(Stu *);
 void output(Stu *);
 void clean(Stu *);

 void main(void)
 {
   Stu student[min];
   input(student);  //相当于传入&student[0]

   output(student);
   clean(student);
 }

 void input(Stu * student)
 {
    char temp[];
    int i=;
    puts("please input name");
    while(i<min & gets(temp) != NULL & temp[] != '\0' )
    {
           student->name = (char *) malloc(strlen(temp)+);
           strcpy(student->name,temp);

           puts("age ?");
           scanf("%d",&student->age);
           puts("score ?");
           scanf("%d",&student->score);

           i++;
           student++;  //指针自加，指向下一个数组单元

           while(getchar() != '\n')
             continue;

          if(i<min)
             puts("next name");
    }

 }

 void output(Stu * student)
 {
    int i=;
    while(i<min){
        printf("%s---%d---%d\n",student->name,student->age,student->score);
        i++;
        student++;
    }

 }

 void clean(Stu * student)
 {
    int i=;
    while(i<min){
         free(student->name);
        i++;
        student++;
    }
