程序查找两个数字之间的差异百分比-yiteyi-C++库

给定两个数字a和b，其中“b”以“a”的某个百分比递增或递减。任务是找出这个百分比。

null

例如：

Input: a = 20, b = 25Output: 25% Difference between 20 and 25 is 5, which is 25 % of 20.(+ve sign indicate increment)Input: a = 25, b = 20Output: -20% ( -ve sign indicate decrement)

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

计算百分比的公式：
