C语言编程
程序功能是输入年份，输出全年的日历。
代码如下
#include<stdio.h>const int D[]={0,31,28,31,30,31,30,31,31,30,31,30,31};int main(){int Year;bool R;scanf("%d",&Year);if ((Year%100!=0&&Year%4==0)||Year%400==0) R=true; else R=false;for (int i=1;i<=12;i++){printf("%d:\n",i);for (int j=0;j<=6;j++) printf("%3d",j);printf("\n");int f;if (i<3) f=Year-1; else f=Year;int g;if (i<3) g=i+13; else g=i+1;int N=1461*f/4+153*g/5+1;int d=(N-621049)%7;for (int j=0;j<d;j++) printf(" ");printf(" 1");for (int j=2;j<=D[i]+(i==2&&R);j++){d++;if (d==7){d=0;printf("\n");}printf("%3d",j);}printf("\n");}return 0;}
运行结果如下
运行结果太长，所以只显示了部分
