1001.A+B Format (20)解题随笔

解题思路：一开始看到题目就觉得应该使用数组方法解题。稍微思考后觉得重点应放在如何每隔三个数字插入一个逗号（相加结果如果是三位数以上的话）。因为A+B的话由题中给出范围可知最多为8位数，故定义一个8个数的数组s[8]。接下来问题就是如何提取和中的每一个位数，最后采取了循环结构：一个数除10取余，赋值给s[i]（i=0;i<8;i++）原数除10之后再除10取余，赋值，直至该数小于10（跳出循环），如此循环。最后输出时也是采取循环结构：将数组倒过来输出，（j=i;j>=0;j++）,通过选择结构，当(j+1)%3==0 && j!=i时输出一个逗号。

bug调试：一开始是忽略了正负号，最后修改时如果为负数的话，先将其变为正数再去执行数组赋值步骤，到最后输出时，再在前面加上负号即可。
