这个改动应该是最小的。12月31号需要增加年份啊。还有要正确使用if else语句啊。

你函数传的是指针，那么调用成员变量要用-> 然后主函数里面要通过&传地址。

input_date(&current_date);
increment_date(&current_date);
output_date(&current_date);

在你的基础上改对了，顺便求个分。。。。

原程序的主要问题有：1、结构体类型指针访问结构体成员的方法不对；2、分支结构的用法不完全正确，导致逻辑出现错误；3、个别地方考虑未完善（如一年最后一天，应考虑年份的递增）。下面是做了修改并通过运行的代码（因题目限制使用指针传递参数，故采用指针方式处理，否则直接采用引用传递更简单）。
