Please compile and run the C program

The full C programming code is at the bottom of the page

Questions

1) The price is not in line with the rest of the price. Please refer to the picture below. Kindly amend the code to make the $3.40 price in line with the rest

2) {Please explain the programming concepts have you used in your coding 3) What are the different functions in the program? What are the functions in terms of their input parameters and what are the functions supposed to achieve and their output? 4) Any features that you have incorporated in your codes to make it better?

5) Pleae write more comments beside the code to let me understand it better.

Thank you
