擁有一個屬於自己的鐘表DIY MY OWN CLOCK！（C語言和EasyX實現）
2020-08-10 10:07:39
首先繪製一個靜態秒針
#include<graphics.h>
#include<conio.h>
#include<math.h>
#define high 480
#define width 640
int main()
{
initgraph(width, high); //註釋亂碼，所以有些地方用英文代替，還望見諒
int x, y; //clock的center
x = width / 2;
y = high / 2;
int secLength; //second hand's長度
secLength = width / 5;
int secEnd_x, secEnd_y; //second hand's末端situation
secEnd_x = x + secLength;
secEnd_y = y;
setlinestyle(PS_SOLID, 2);
setcolor(WHITE);
line(x, y, secEnd_x, secEnd_y);
getch();
closegraph();
return 0;
}
秒針轉動
#include<graphics.h>
#include<conio.h>
#include<math.h>
#define high 480
#define width 640
#define PI 3.14159
int main()
{
initgraph(width, high); //註釋亂碼，所以有些地方用英文代替，還望見諒
int x, y; //clock的center
x = width / 2;
y = high / 2;
int secLength; //second hand's長度
secLength = width / 5;
int secEnd_x, secEnd_y; //second hand's末端situation
float secAngle = 0; //second hand's角度
while(1)
{
secEnd_x = x + secLength * sin(secAngle);
secEnd_y = y - secLength * cos(secAngle);
setlinestyle(PS_SOLID, 2);
setcolor(WHITE);
line(x, y, secEnd_x, secEnd_y);
Sleep(1000);
setcolor(BLACK);
line(x, y, secEnd_x, secEnd_y);
secAngle += (2 * PI) / 60; //在C/C++中需要轉爲弧度才能 纔能正常
}
getch();
closegraph();
return 0;
}
實時轉動的秒針
GetLocalTime(&ti)可以獲取當前時間
#include<graphics.h>
#include<conio.h>
#include<math.h>
#define high 480
#define width 640
#define PI 3.14159
int main()
{
initgraph(width, high); //註釋亂碼，所以有些地方用英文代替，還望見諒
int x, y; //clock的center
x = width / 2;
y = high / 2;
int secLength; //second hand's長度
secLength = width / 5;
int secEnd_x, secEnd_y; //second hand's末端situation
float secAngle = 0; //second hand's角度
SYSTEMTIME ti; //define變數儲存當前時間
while(1)
{
GetLocalTime(&ti);
secAngle = ti.wSecond * 2 * PI / 60;
secEnd_x = x + secLength * sin(secAngle);
secEnd_y = y - secLength * cos(secAngle);
setlinestyle(PS_SOLID, 2);
setcolor(WHITE);
line(x, y, secEnd_x, secEnd_y);
Sleep(1000);
setcolor(BLACK);
line(x, y, secEnd_x, secEnd_y);
}
getch();
closegraph();
return 0;
}
增添時針、分針
#include<graphics.h>
#include<conio.h>
#include<math.h>
#define high 480
#define width 640
#define PI 3.14159
int main()
{
initgraph(width, high);
int x, y;
x = width / 2;
y = high / 2;
int secLength = width / 4;
int minLength = width / 5;
int hourLength = width / 6;
int secEnd_x, secEnd_y;
int minEnd_x, minEnd_y;
int hourEnd_x, hourEnd_y;
float secAngle, minAngle, hourAngle;
SYSTEMTIME ti; //儲存當前時間
while(1)
{
GetLocalTime(&ti);
secAngle = ti.wSecond * 2 * PI / 60;
minAngle = ti.wMinute * 2 * PI / 60;
hourAngle = ti.wHour * 2 * PI / 12; //1圈12小時
secEnd_x = x + secLength * sin(secAngle);
secEnd_y = y - secLength * cos(secAngle);
minEnd_x = x + minLength * sin(minAngle);
minEnd_y = y - minLength * cos(minAngle);
hourEnd_x = x + hourLength * sin(hourAngle);
hourEnd_y = y - hourLength * cos(hourAngle);
setlinestyle(PS_SOLID, 1);
setcolor(WHITE);
line(x, y, secEnd_x, secEnd_y);
setlinestyle(PS_SOLID, 4);
setcolor(BLUE);
line(x, y, minEnd_x, minEnd_y);
setlinestyle(PS_SOLID, 6);
setcolor(RED);
line(x, y, hourEnd_x, hourEnd_y);
Sleep(1000);
setcolor(BLACK);
setlinestyle(PS_SOLID, 2);
line(x, y, secEnd_x, secEnd_y);
setlinestyle(PS_SOLID, 4);

setlinestyle(PS_SOLID, 6);
line(x, y, hourEnd_x, hourEnd_y);
}
getch();
closegraph();
return 0;
