计算日出日落时间可以通过多种编程语言实现,以下是几种常见语言的方法:
C 语言
```c
include include define PI 3.1415926 int days_of_month_1[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; int days_of_month_2[] = {31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; long double h = -0.833; void input_date(int c[]) { int i; printf("Enter the date (form: YYYY MM DD): "); for (i = 0; i < 10; i++) { scanf("%d", &c[i]); } } void input_glat(int c[]) { int i; printf("Enter latitude (range: -90 to 90 degrees, form: DD MM SS): "); for (i = 0; i < 10; i++) { scanf("%d", &c[i]); } } void input_glong(int c[]) { int i; printf("Enter longitude (west is negative, form: DD MM SS): "); for (i = 0; i < 12; i++) { scanf("%d", &c[i]); } } long double calculate_sunrise_sunset(int year, int month, int day, int lat, int lon) { // ... (省略了具体的计算代码) } int main() { int date; int lat; int lon; input_date(date); input_glat(lat); input_glong(lon); long double sunrise = calculate_sunrise_sunset(date, date, date, lat, lon); long double sunset = calculate_sunrise_sunset(date, date, date, lat, lon); printf("Sunrise: %.2Lf\n", sunrise); printf("Sunset: %.2Lf\n", sunset); return 0; } ``` Java
