Some Questions

If you are completely satisfied that you have got the WOTCOST.C program working correctly and satisfactorily, then you can go on to consider the following questions.

• Are there any restrictions on the numbers that this program can deal with? Try to find out using very big and very small numbers - and anything else you can think of.

• What happens if you feed in negative numbers to this program? What should happen (in your opinion)?

• What happens if you feed in too many numbers? Too few? What should happen?

• What happens if you feed in non-numbers? What should happen?

• If you change things in the program it will generally cause compiler and/or linker errors. Try to find what is the simplest, most innocuous, change you can make which gives rise to the greatest number of weird and incomprehensible error and warning messages at compile time.
