C语言，终端显示为什么会多个退格

Question

循环后两次为什么多两个退格

#include<stdio.h>
int main()
{
    struct student{
        int num;
        char *name;
        char sex;
        int age;
    }stu[5]={{1001,"lihua",'F',18},{1002,"liuxing",'M',19},{1003,"huangke",'F',19},{1004,"fengshou",'F',19},{1005,"Wangming",'M',18}};
    struct student *p=stu;
    int i;
    printf("Num\tName\t\t\tSex\tAge\t\n");
    for(p=stu;p<stu+5;p++)
    printf("%d\t%s\t\t\t%c\t%d\n",p->num,p->name,p->sex,p->age);  

}

Answer 1

后面2个名字太长，自动多了个\t，\t有时候不好使
可以指定输出宽度

printf("%-8s%-15s%8s%8s\n", "Num", "Name", "Sex", "Age");
  for (p = stu; p < stu + 5; p++)
    printf("%-8d%-15s%8c%8d\n", p->num, p->name, p->sex, p->age);
