Q. Write an interactive program to calculate compound interest.
Ans.
/*c program for calculate compound interest*/
#include<stdio.h>
#include<math.h>
#include<conio.h>
int main()
{
float p,rate,time,ci;
printf("Enter principal amount : ");
scanf("%f", &p);
printf("Enter interest rate : ");
scanf("%f", &rate);
printf("Enter time period in year : ");
scanf("%f", &time);
//calculate ci
ci=p*(pow((1+rate/100),time)-1);
printf("\nCompound interest = %f",ci);
return 0;
}
Output :-
Enter principal amount : 48500
Enter interest rate : 6
Enter time period in year : 2
Compound interest = 5994.600098
good structured program
ReplyDeleteWhy do we put -1? Please tell
DeletePower (x, -1)
DeleteIs the same as x raised to -1
Or mathematically: (1/x)
Why we put -1 here
ReplyDelete-1 mention in the calculating formula of Compound interest, so it is not the part of C programming language.
