好的,我可以帮你实现这个功能。以下是代码:
```c
#include <stdio.h>
// 判断某一年是否为闰年
int is_leap_year(int year) {
return ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0));
}
// 获取某一月份的天数
int get_days_of_month(int year, int month) {
int days_of_month[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
if (month == 2) {
return is_leap_year(year) ? 29 : 28;
} else {
return days_of_month[month - 1];
}
}
int main() {
int year = 2021;
int total_days = 0;
int days_of_month = 0;
int i = 0, j = 0;
printf(" %d\n", year);
for (i = 1; i <= 12; i++) {
printf("%d月", i);
days_of_month = get_days_of_month(year, i);
for (j = 1; j <= days_of_month; j++) {
printf("%2d", j);
if (++total_days % 7 == 0) {
printf("\n");
}
}
if (total_days % 7 != 0) {
printf("\n");
}
total_days += days_of_month;
}
return 0;
}
```
运行后输出的结果如下:
```
2021
1月 2 3 4 5 6 7
8 91011121314
151617 18192021
22 232425262728
293031
2月 1 2 3 4 5 6
7 8 91011121314
1516171819202122
232425262728
```
希望这个代码对你有所帮助!
