C语言实现动态万象时钟操作步骤及源码

C语言实现动态万象时钟操作步骤及源码需要先看清适用场景和关键步骤，避免只记结论却忽略实际限制。

一、项目介绍

这是一个用C语言绘制的动态万象时钟。

编译环境：Visual Studio2019

第三方库：Easyx2022 注意需要提前安装easyX，如没有基础可以先了解easyX图形编程

二、运行截图

三、部分代码

1.引入图形头文件

#include <graphics.h>

2.定义窗口大小

#define Width 550#define Height 550

3.设定圆的结构

struct TimeCircle{int fors;// 每一圈分成的份数int R;// 圈的半径double NextTime;// 上一个时刻时间double Radian;// 累加的弧度};int main(){initgraph(Width, Height);SYSTEMTIME ti;TimeCircle TC[7];TCHAR str[25];for (int i = 0; i < 7; i++){TC[i].R = (i + 1) * 35;TC[i].Radian = 0;TC[i].NextTime = 0;switch (i){case 0:TC[i].fors = 1; break;// 年case 1:TC[i].fors = 12; break;// 月case 2:TC[i].fors = 30; break;// 日case 3:TC[i].fors = 7; break;// 周case 4:TC[i].fors = 24; break;// 时case 5:TC[i].fors = 60; break;// 分case 6:TC[i].fors = 60; break;// 秒}}BeginBatchDraw();while (true){GetLocalTime(&ti);TC[2].fors = monthdasy(ti.wYear, ti.wMonth);for (int j = 0; j < 7; j++){if (TC[5].NextTime != ti.wMinute){TC[5].NextTime = ti.wMinute;TC[5].Radian = 0;}else{TC[5].Radian = TC[5].Radian + (2 * PI / TC[5].fors - TC[5].Radian) / 10;}if (TC[6].NextTime != ti.wSecond){TC[6].NextTime = ti.wSecond;TC[6].Radian = 0;}else{TC[6].Radian = TC[6].Radian + (2 * PI / TC[6].fors - TC[6].Radian) / 10;}for (int i = 0; i < TC[j].fors; i++){switch (j){case 0: _stprintf_s(str, _T("%d年"), ti.wYear); break;case 1: _stprintf_s(str, _T("%d月"), (i + ti.wMonth) % TC[j].fors ? (i + ti.wMonth) % TC[j].fors : TC[j].fors); break;case 2: _stprintf_s(str, _T("%d号"), (i + ti.wDay) % TC[j].fors ? (i + ti.wDay) % TC[j].fors : i + ti.wDay); break;case 3: str[0] = L"周"[0];    str[1] = L"日一二三四五六"[(i + ti.wDayOfWeek) % 7];    str[2] = L""[0]; break;case 4: _stprintf_s(str, _T("%d时"), (i + ti.wHour) % TC[j].fors); break;case 5: _stprintf_s(str, _T("%d分"), (i + ti.wMinute) % TC[j].fors); break;case 6: _stprintf_s(str, _T("%d秒"), (i + ti.wSecond) % TC[j].fors); break;}DrawCircle(str, i, TC[j].fors, TC[j].R, TC[j].Radian);;}}FlushBatchDraw();cleardevice();}EndBatchDraw();return 0;}
