Explanation

Interest Calculation Function:
- calculateSimpleInterest(double principal, double rate, double time): This function calculates the simple interest
  - Parameters:
    - principal: The initial amount of money.
    - rate: The annual interest rate (in percentage).
    - time: The time period (in years).
  - Return Value: Returns the calculated interest.
Main Function:
- Prompts the user to enter the principal amount, annual interest rate, and time period.
- Calls calculateSimpleInterest() to compute the interest.
- Uses fixed and setprecision(2) from the <iomanip> library to format the output to two decimal places.
- Displays the calculated simple interest.

Notes:

The fixed and setprecision(2) settings ensure that the output is displayed with two decimal places for better readability.

This program calculates the simple interest based on user input and provides a straightforward way to understand the concept of simple interest.
