判断第几天 （C语言代码）

解题思路:

注意事项:

参考代码:

#include<stdio.h>

int main(void)

{

int * days;

int x, y, z, i, total;

while (scanf("%d/%d/%d", &x, &y, &z) == 3)

{

total = 0;

i = 0;

if ((!(x%4)) && (x%100) || (!(x%400)))

    {

    int days[] = {0,31,29,31,30,31,30,31,31,30,31,30,31};

    for (i = 1; i < y; i++)

    {

    total += days[i];

}

total += z;

printf("%d\n", total);

}

else

{

int days[] = {0,31,28,31,30,31,30,31,31,30,31,30,31};

    for (i = 1; i < y; i++)

    {

    total += days[i];

}

total += z;

printf("%d\n", total);

}

}

return 0;

}
