又是水题,枚举每天的情况

 1 #include <stdio.h>
 2 
 3 int month[12]={31,28,31,30,31,30,31,31,30,31,30,31},week[7];
 4 int count,n;
 5 
 6 int main()
 7 {
 8     int i=0,j=0,k=0;
 9     scanf("%d",&n);
10     count=1;//天数计数
11     for(i=1900;i<1900+n;i++)
12     {
13         if ((((i%4)==0)&&((i%100)!=0))||((i%400)==0)) month[1]=29;
14         else month[1]=28;
15         count=count%7;
16         for(j=1;j<=12;j++)
17         {
18             for(k=1;k<=month[j-1];k++)
19             {
20                 if(13==k) week[count%7]++;
21                 count++;
22             }
23         }
24     }
25     printf("%d ",week[6]);
26     for(i=0;i<6;i++)
27     {
28         printf("%d",week[i]);
29         if(i!=5) printf(" ");//要不然格式错。。。
30     }
31     printf("\n");
32     return 0;
