"Check the return value from timesTable. If it is less zero then print out an error message to the user."


I don't know what this means

Does it involve that return(0); thing we have at the end of every function? timesTable is a function. The only return it has in it is the return(0); thing.


I've tried googling this but I keep getting results for java and other languages. I've tried looking in the text book but the index doesn't have anything. I've looked through just about every single example in the book, but I can't find one that looks like it deals with the return value.


Please help
