请问这一题怎么解决?(用c语言)9.2. Exercise
Calling time (NULL) gives you a large integer. Use this value to calculate today's year, date, hours, and minutes.
Simplifying assumption:we pretend that each year has exactly365 days. The 15th of March is therefore day 83 in year 2011. (use that date to figure out today's "day number")(hint: how many seconds are there in a day?)
You cannot use struct for this assignment.
You cannot use any time-based functions from the standard library such asasctime or strftime.
You must use one function to calculate the year and day(pass inthe total seconds, and a reference to the year and day).
You must use a separate function to calculate the hours andminutes.(again, pass the total seconds, and a reference to the hours and minutes)
You must use a separate function to print the time; this functioncan only take as arguments the year, day, hour, and minutes.
(optional: handle leap-years correctly, and print the month as well). 这道题要求你使用C语言来计算当前的年份、日期、小时和分钟。我们可以利用调用time(NULL)函数返回的大整数来进行计算。
首先,我们需要使用一个函数来计算年份和日期。我们可以假设每一年都有365天,并且以2011年3月15日为基准,那么今天是第几天。我们可以通过计算今天到2011年3月15日之间的秒数差来得出答案。提示一下,一天中有多少秒呢?
然后,我们需要使用另一个函数来计算小时和分钟。同样地,我们可以通过将总秒数转换为小时和分钟来得到答案。
最后,我们需要使用一个函数来打印年份、日期、小时和分钟。这个函数只能接受年份、日期、小时和分钟作为参数。
这个题目是可选的,你可以选择正确地处理闰年,并打印出月份。
下面是一个实现的例子:
#include <stdio.h>
void calculateYearAndDay(int totalSeconds, int *year, int *day) {
*year = totalSeconds / (365 * 24 * 60 * 60);
*day = (totalSeconds % (365 * 24 * 60 * 60)) / (24 * 60 * 60);
}
void calculateHoursAndMinutes(int totalSeconds, int *hours, int *minutes) {
*hours = (totalSeconds % (24 * 60 * 60)) / (60 * 60);
*minutes = (totalSeconds % (60 * 60)) / 60;
}
void printTime(int year, int day, int hours, int minutes) {
printf("Today's date is ");
printf("%d-%d, ", year + 2011, day + 15);
printf("%02d:%02d\n", hours, minutes);
}
int main() {
int totalSeconds = time(NULL);
int year, day, hours, minutes;
calculateYearAndDay(totalSeconds, &year, &day);
calculateHoursAndMinutes(totalSeconds, &hours, &minutes);
printTime(year, day, hours, minutes);
return 0;
}
这个例子中,我们使用time(NULL)函数来获取总秒数,然后将它传递给计算年份和日期的函数calculateYearAndDay(),计算小时和分钟的函数calculateHoursAndMinutes(),最后将结果传递给打印时间的函数printTime()。
希望这个例子可以帮助你理解并解决这道题目!
