**C Program to find simple interest: **Simple interest is a type of fee that is charged (or paid) only on the amount borrowed (or invested), and not on past interest.

The sum of principal and the interest is called Amount.

Amount (A) = Principal (P) + Interest (I)

The Simple Interest (I) occurred over a time period (T) for R% (rate of Interest per annum)
