定义学生基本信息

①输出所有学生信息

②删除某个学生后，输出所有学生信息

③修改某个学生信息后，输出所有学生信息

④查找某个学生的信息

 main.c

#include"k11*.h"
int main(int argc, const char *argv[])
{struct student p[4]={{"可乐",17,88},{"雪碧",18,99},{"果粒",16,100},{"芬达",23,66}};	output_p(p,4);del_p(p,4);fix_p(p,2);find_p(p,2);return 0;
}

k11.c

#include"k11*.h"void output_p(struct student p[],int len)
{printf("---学生信息如下---\n\n");for(int i=0;i<len;i++){printf("第%d个学生: 姓名:%s  年龄:%d  成绩:%ld\n",i+1,(p+i)->name,(p+i)->age,(p+i)->sorce);}printf("----------------------------------------");putchar(10);
}
