I have been trying get the right code with C$++$ style but its wrong and not compiling right.

The local flying$-$disc shop sells premium disc$-$golf and ultimate $($Frisbee$)$ discs. The disc$-$golf discs retail for $$15\mathrm{.}88$ and the ultimate discs retail for $$12\mathrm{.}96$ each. Sample Output $($user input is in yellow$)$

$0$ is an invalid number of discs.

Sample Output $($user input is in yellow$)$

Welcome to the Flying$-$Disc Shop!

Enter $\text{'}$u$\text{'}$ for ultimate discs and $\text{'}$g$\text{'}$ for disc golf: $r$

Invalid disc type.

Submit only your file named FlyingDiscs.cpp$.$

Quantity discounts are given as follows:

Number $of$ Discs Discount

$5-9,8\%$

$10-19,16\%$

$20-29,24\%$

$30or$ more $32\%$

Write a program that asks the cashier if the customer wishes to purchase disc$-$golf or ultimate discs. The cashier enters a $\text{'}$u$\text{'}$ or $\text{'}$U$\text{'}$ for ultimate and $\text{'}$g$\text{'}$ or $\text{'}$G$\text{'}$ for disc

golf; all other input$-$output the error message, "Invalid disc type." exit the program. $($Use a switch statement to check the user's input and use return $0$; in the

switch statement to end the program.$).$ If the input was valid, the program should then prompts the user for the number of discs. If the number is positive, the

program displays the disc type, quantity, price per disc $($after any discount$),$ the total savings, and total price $($with exactly $2$ decimal places$).$ Otherwise, the program

displays the error message, $"$ X is an invalid number of discs" $($where X is the user$-$inputted number$).$

In your implementation, avoid duplicating your code; arrange the program logic so that no statements are repeated. $($Hint: a single string variable is useful to hold

either "Ultimate Disc" or "Disc$-$Golf Disc"$)$ Also, define and use constants for the retail prices $($i$.$e$.,$ DISC$\_$GOLF$\_$RETAIL, ULTIMATE$\_$RETAIL$).$ You may use

additional constants if you choose.
