The code you sent has 1 error but hopefully you can help to get this code running with proper output. Thx.

float sale_price; The error states: 'float sale_price:redefinition'?

Hi. The code you sent has 57 errors? can you help? I use Visual Studio Code compiler 

Define input and output devices with proper examples.

Hi. This code hass errors when I add first cite. Thx
