Question $2$: Simple Interest Calculator

Problem Statement: Write a C$++$ program that calculates the simple interest on a loan.

The program should prompt the user to enter the principal amount, the annual interest rate

$($as a percentage$),$ and the time period in years. The program should then calculate and

display the simple interest using the formula:

$=\backslash$times $\backslash$times $$

$100$

Requirements:

$$ Prompt the user to enter the principal amount, interest rate, and time period.

$$ Use the formula to calculate the simple interest.

$$ Display the calculated simple interest.

$$ Handle cases where any of the inputs $($principal$,$ rate, or time$)$ are less than or equal

to zero, and display an appropriate error message.

Example Output $1$:

Enter the principal amount: $1000$

Enter the annual interest rate $($in $\%)$: $5$

Enter the time period in years: $3$

The simple interest is: $150$

Example Output $2$:

Enter the principal amount: $1000$

Enter the annual interest rate $($in $\%)$: $0$

Enter the time period in years: $3$

Error: All values must be positive numbers
