#include<stdio.h>
#include<math.h>
int main()
{
float amount, rate, intrest, time, ci, a;
/*Reading amount, rate of intrest
and period in years from user
*/
printf("Type the amount : ");
scanf("%f", &amount);
printf("Type the interest rate : ");
scanf("%f", &rate);
printf("Type the period in years: ");
scanf("%f", &time);
intrest = 1+(rate/100);
// ci=pow(intrest,time);
ci = 1;
for(a = 1; a <= time; a++)
ci = ci * intrest;
ci = amount * ci - amount;
printf("Your compound interest is : %.2f", ci);
return 0;
}
Result:
Type the amount : 5000
Type the interest rate : 10
Type the period in years: 1
Your compound interest is : 500.00
