#include<stdio.h>
#define week_day 7
#define name_len 10
char weekday[week_day][name_len]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
int main()
{
    char course_name[20];
    int days;
    char time[6];
    int i;
    scanf("%s",course_name);
    scanf("%s",&days);
    scanf("%s",time);
    for(i=0;i<week_day;i++)
        printf("%10s",weekday[i]);
    printf("\n%s",time);
    for(i=0;i<10*days;i++)
        printf(" ");
    printf("%s\n",course_name);
    return 0;}
能不能逐句分析一下，有点不理解

非常抱歉，时间匆忙忘记说了，主要是char weekday[week_day][name_len]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};和 for(i=0;i<10*days;i++)这两句，后一句为什么10*days

这是这个程序的要求：要求用户输入一个代表课程名称的字符串，表示星期几的整数以及表示该课程上课节次串，输出该节次对应的课程表
