Assignment:
Q: Modify the existing code (separate attachment) to be more orderly in its output appearance. Basically so that the displays are similar to what is below in the samples.
Right now, I get this error when attempting to compile in Miracle C:
c:program filesmiracle cnewweek4.c: line 18: wrong # args in function call
'{ printf("Enter name for product %d: ",i+1)'
aborting compile
If I add in #include at the beginning, the program runs, but when it comes to the point where customer pick their products the display is very is disorganized and looks like this:
Products: n1. grapes:n2. corn:n3. oranges:n4. potatoes:n5. beans:nnSelect a product or 0 to complete
And once selecting 0 to complete checkout, it looks like this:checkoutn0
Purchase Total: 0.00nDiscount Total: 0.00nTotal Amount Due: 0.00nnThank you for shopping!nnC for checkout or X for exit:
I would to have it look like the samples below instead of strung out if possible and is there a way to get the "n" out of the display?
1) Include comments within the program to document the program internally.
2) Verify the program compiles and runs.
3) Thank you very much for your help.
