寻找复利的程序-yiteyi-C++库

什么是“复利”？ 复利指贷款或存款本金加上的利息，或者换句话说，利息。它是利息再投资的结果，而不是支付利息，因此下一个时期的利息将由本金加上之前累计的利息赚取。复利是金融和经济学中的标准利率。复利可能与单利形成对比，单利的利息不计入本金，因此没有复利。 复利公式：

null

每年计算复利的公式如下： 金额=P（1+R/100） ^T

复利=金额–P 哪里 P是原则金额 R是速率和 T是时间跨度

伪代码：

Input principle amount. Store it in some variable say principle.Input time in some variable say time.Input rate in some variable say rate.Calculate Amount using formula, Amount = principle * (1 + rate / 100) ^time).Calculate Compound Interest using Formula.Finally, print the resultant value of CI.

例子：

Input : Principle (amount): 1200        Time: 2        Rate: 5.4Output : Compound Interest = 133.099243
