全屏幕显示时钟（同时具备电子表和机械表的功能）.docx

特别声明：此时钟源程序来自网上，经过本人两处修改：1 时针，分针能够随秒针而动2 能够显示电子手表#include#include#include#define pi 3.1415926#include#define X(a,b,c) x=a*cos(b*c*pi/180-pi/2)+300;/*减PI/2是求出与右边水平轴的夹角的幅度数*/#define Y(a,b,c) y=a*sin(b*c*pi/180-pi/2)+240;#define d(a,b,c) X(a,b,c);Y(a,b,c);line(300,240,x,y)#define M 270#define N 350#define displaytime() sprintf(msg,%02.0f:%02.0f:%02.0f,h,m,s);outtextxy(M,N,msg);void init()int i,l,x1,x2,y1,y2;setbkcolor(1);circle(300,240,200);circle(300,240,205);circle(300,240,5);for(i=0;i60;i+) if(i%5=0) l=15; else l=5; x1=200*cos(i*6*pi/180)+300;/*每6度作为一个刻度*/ y1=200*sin(i*6*pi/180)+240; x2=(200-l)*cos(i*6*pi/180)+300; y2=(200-l)*sin(i*6*pi/180)+240; line(x1,y1,x2,y2); setcolor(GREEN);rectangle(M-5,N-5,M+65,N+15);/*画表的刻度*/main()int x,y;int gd=VGA,gm=2;float h,m,s;struct time t1;char msg80;void *buf;int size;initgraph(&gd,&gm,e:tc);init();setwritemode(1);gettime(t);h=t0.ti_hour;m=t0.ti_min;s=t0.ti_sec;setcolor(7);d(150,h,30);setcolor(14);d(170,m,6);setcolor(4);d(190,s,6);/*初始化秒 分 时针*/setcolor(7);displaytime();while(!kbhit()/*击打键盘则退出循环*/ while(t0.ti_sec=s) gettime(t);/*延迟一秒钟*/ setcolor(1); displaytime(); sound(400); delay(70); sound(200); delay(30); nosound();/*发出声响*/ setcolor(4); d(190,s,6); s=t0.ti_sec; d(190,s,6);/*画新的秒针线*/ setcolor(14); d(170,m,6); m=t0.ti_min+s/60.0; d(170,m,6);/*画新的分针线*/ setcolor(7); d(150,h,30); h=t0.ti_hour+m/60.0; d(150,h,30);/*画新的时针线*/ sound(1000);/*发出声响*/ delay(240); nosound(); delay(140); sound(200
