使用 C 语言公式计算利息金额
cserver side programmingprogramming
问题
编写一个 C 程序来计算几年后增加的存款金额和利息
解决方案
计算利息的公式是 −
M=((r/100) * t); A=P*exp(M);
其中 r= 利率
t=年数
P=要存入的金额
M=临时变量
A= 计息后的最终金额
算法
START 步骤 1:声明双精度变量 步骤 2:读取要存入的金额 步骤 3:读取利率 步骤 4:读取要存入的年限 步骤 5:计算计息后的最终金额 I. M=((r/100) * t); II. A=P*exp(M); 步骤 6:打印最终金额 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;
}
输出
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
