Question 3
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
