name 和 major字段希望你能用数组，因为你很有可能要修改它。

struct student
        {
            int num;
            char *name;
            char sex;
            char *major;
            int age;
        }boy[6]={{1,"郑银祥",'M',"计科",21},
                 {2,"周翔",'M',"计科",19},
        {3,"大明星",'M',"软工",20},
        {4,"小广东",'M',"计科",20},
        {5,"范欣晨",'M',"计科",20},
        {6,"宫成",'M',"计科",20}};
            
        struct student *ps;
        printf("床号\t姓名\t性别\t专业\t年龄\t\n");
        for(ps=boy;ps<boy+6;ps++)
        printf("%d\t%s\t%c\t%s\t%d\n",ps->num,ps->name,ps->sex,ps->major,ps->age);

同意二楼

额。。。楼主里面好多错误，，，人数和数组就不对，，自己看一下修改的吧，“男”是字符串不是字符。

#include<stdio.h>

void main()
{
     struct student
         {
             int num;
             char name[10];
             char sex[4];
             char major[10];
             int number;
         }boy[5]={{1,"郑银祥","男","计科",21},
                  {2,"周翔","男","计科",19},
         {3,"大明星","男","软工",20},
         {4,"小广东","男","计科",20},
         {5,"范欣晨","男","计科",20}};
         
         
         struct student *ps;
         printf("床号\t姓名\t性别\t专业\t年龄\t\n");
         for(ps=boy;ps<boy+5;ps++)
             printf("%d\t%s\t%s\t%s\t%d\n",ps->num,ps->name,ps->sex,ps->major,ps->number); 
}

惭愧，这些还没讲，自己看书学的点

结构里的sex元素是字符变量（按你定义的），而却赋了字符串初值……

为什么要把要用"M"才行呢？
