In this tutorial, we will write a program to find the Simple Interest in C. And the formula to calculate the Simple Interest (SI) is:

`SI = ((p * r * t) / 100)) where, p = Principal r = Rate of Interest t = Time Period`

Explanation:
The program takes the user input for Principal, Rate, and Time, calculates the result, and displays the result on the screen.
