Your program will first input L or N as the tier of the customer denoting Loyal or New, respectively. The

user should be able to enter either lowercase or uppercase letters. If anything other than L$/$l$/$N$/$n is given

as input, the program will show an appropriate error message and will exit without taking further inputs.

After the successful input of the customer tier, the program will take the total purchase price $($double type$)$

as input. There should be check for negative input. If the input value is negative, the program will exit

showing appropriate error message without calculating the final payable amount. For a positive purchase

price, the appropriate discount amount $($based on Table $1)$ will be applied, and then $13\%$ sales tax will be

added to calculate the final payable amount. The applied discount rate, the tax amount $($currency format$),$

and the final payable amount $($currency format$)$ will be shown as the output.

Do NOT use Switch statements in your program. Your program must show appropriate prompts to take

inputs form the user. Proper output message needs to be written on the console while showing the output.

Include enough comments in the program to explain your code.
