a = new int[] {0,1500,4500,9000,35000,55000,80000};應納稅所得額是按升序排列的
計算時要逆序進行

你的Ｂ陣列值錯了。
應是如上值。

你的Ｂ陣列值錯了。
應是如上值。 0.03,你搞成0.3了。

計算時按逆序進行是什么意思。。。uj5u.com熱心網友回復：
8000055000
35000
9000
4500
1500
uj5u.com熱心網友回復：
還得把 if (income <= (theRecord.upperLimit + m_dThreshold))中的<=換成>=，并加上上面說的降序排列才能成功喲！uj5u.com熱心網友回復：
這個思路好，我也做過這個，就是用正序做的，還寫了一個很麻煩的演算法
用逆序做就很簡單了。
