The first program

The second program
Lesson Learned: 将

daysInMonth[]的内容拷贝到leapYearDaysInMonth[]的时候忘记将闰二月改为29天... 看来每次写完一条语句都应该verify一下。这个看似浪费时间,却真正能够减少debugging的大量时间呀

The third program
Input:

1981 8
Output:

Lesson Learned: 居然犯下如此低级的C语言数组下标错误,将pDaysInMonth[month-1]写成了pDaysInMonth[month]。哎,人类语言从1为下标,而C语言从0开始下标。要将此作为我的一个Programming Alarm。。。
