编程入门]结构体之时间设计 想了好久

解题思路:

注意事项:

参考代码:

#include<iostream>

using namespace std;

struct time

{

int year;

int month;

int day;

};

int main()

{

struct time t1;

cin >> t1.year;

cin >> t1.month;

cin >> t1.day;

int sum = 0,sum1=0, sum2 = 0;

int total = 0;

if ((t1.year % 400 != 0) || (t1.year % 4 != 0 && t1.year % 100 == 0))

{

t1.month = t1.month - 1;

while (1)

{

if (t1.month == 1 || t1.month == 3 || t1.month == 5 || t1.month == 7 || t1.month == 8 || t1.month == 10 || t1.month == 12)

{

sum += 31;

}

else

{

if (t1.month == 2)

{

sum1 = 28;

}

else

{

sum2 += 30;

}

}

t1.month--;

if (t1.month < 1)

{

break;

}

}

total = sum + sum1+ sum2;

}

else

{

t1.month = t1.month - 1;

while ( 1)

{

if (t1.month == 1 || t1.month == 3 || t1.month == 5 || t1.month == 7 || t1.month == 8 || t1.month == 10 || t1.month == 12)

{

sum += 31;

}

else

{

if (t1.month == 2)

{

sum1 = 29;

}

else

{

sum2 += 30;

}

}

t1.month--;

if (t1.month < 1)

{

break;

}

}

total = sum + sum1+ sum2;

}

cout << total+t1.day << endl;

system("pause");

}
