Calculate interest amount by using formula in C language
Problem
Write a C program to calculate the deposited amount incremented after some years with interest
Solution
The formula for calculating interest is −
M=((r/100) * t); A=P*exp(M);
Where r= rate of interest
t=no. of years
P=amount to be deposited
M=temporary variable
A= Final amount after interest
Algorithm
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
Example
#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;
}Output
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
