要编写一个计算日出日落时间的程序,你可以选择不同的编程语言来实现。以下是使用C语言和Java两种语言分别编写的示例代码:
C语言示例
```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°): "); for (i = 0; i < 10; i++) { scanf("%d", &c[i]); } } void input_glong(int c[]) { int i; printf("Enter longitude (west is negative, range: -180° to 180°): "); for (i = 0; i < 10; i++) { scanf("%d", &c[i]); } } // Function to calculate sunrise and sunset times void calculate_sunrise_sunset(int year, int month, int day, int lat, int lon, int *sunrise, int *sunset) { // ... (省略了具体的计算公式和代码) } int main() { int date, lat, lon; int sunrise, sunset; input_date(date); input_glat(lat); input_glong(lon); calculate_sunrise_sunset(date, date, date, lat, lon, &sunrise, &sunset); printf("Sunrise time: %d:%02d\n", sunrise / 10000, sunrise % 10000); printf("Sunset time: %d:%02d\n", sunset / 10000, sunset % 10000); return 0; } ``` Java示例
