Question

Program should print a message indicating that the number must be negative if the user enters a positive number or zero and prompt them again. Your program should continue this behavior until you have received a negative integer. Use a loop to trap the user until you get the value that you want. You should also examine the return value of scanf to see if you were able to successfully read an integer at all and if not then you should attempt to clear the keyboard buffer by reading characters from the keyboard up to and including a new line. In fact, even if you successfully read a negative integer or zero you should clear the buffer afterwards. Use a function that shown in class to clear the buffer in these cases. Remember that scanf evaluates as the number of successful conversions. In this case, if it evaluates as 1 then you successfully read an integer but if it evaluates as zero then it failed in some way.
