使用 C 語言中的公式計算利息金額
問題
編寫一個 C 程式,以計算若干年後本金增加利息後的金額
解決方案
計算利息的公式為:
M=((r/100) * t); A=P*exp(M);
其中 r = 利率
t = 年數
P = 要存放的金額
M = 臨時變數
A = 有利息後的最終金額
演算法
START Step 1: declare double variables Step 2: read amount to be deposited Step 3: read rate of interest Step 4: read years you want to deposit Step 5: Calculate final amount with interest I. M=((r/100) * t); II. A=P*exp(M); Step 6: Print final amount STOP
示例
#include<stdio.h>
#include<math.h>
#include<ctype.h>
int main(){
double P,r,t,A,M;
printf("amount to be deposit in the bank: ");
scanf("%lf",&P);
printf("
enter the rate of interest:");
scanf("%lf",&r);
printf("
How many years you want to deposit:");
scanf("%lf",&t);
M=((r/100) * t);
A=P*exp(M);
printf("
amount after %0.1lf years with interest is:%0.2lf",t,A);
return 0;
}輸出
amount to be deposit in the bank: 50000 enter the rate of interest:6.5 How many years you want to deposit:5 amount after 5.0 years with interest is:69201.53
