The simple interest on a loan is calculated by the formula
interest = principal * rate * days / 365;
The preceding formula assumes that rate is the annual interest rate, and therefore includes the division by 365 (days). Develop a program that will input principal, rate and days for several loans, and will calculate and display the simple interest for each loan, using the preceding formula.
#include<iostream.h>
#include <stdio.h>
int main(void)
{
int principal, rate, days, interest;
printf("enter principal\n");
scanf("%d", &principal);
printf(" enter rate\n");
scanf("%d", &rate);
printf(" enter days ");
scanf("%d", days);
interest = principal * rate * days / 365;
printf(" the interest is %d");
system("pause");
return 0;
}
What is missing from this c program. please help me.... thanks?No & in front of days in scanf
interest should probably not be integer in real life because of div by 365.
What is missing from this c program. please help me.... thanks?The corrected version.
#include <stdio.h>
int main(void)
{
double principal, rate, interest;
int days;
printf("enter principal $");
scanf("%lf", &principal);
printf(" enter rate :");
scanf("%lf", &rate);
printf(" enter days ");
scanf("%d", &days);
interest = principal * rate * days / 365.0;
printf(" the interest is %f", interest);
printf("Press Enter>");
fflush(stdin);
getchar();
return 0;
}
