C validating input char dream and christina milian dating
The way I organized it, the user inputs a value (read into the variable int user_input), and the program does something based on that. I cut out from the beginning and the end, but I'm assuming just about everything but the while() loop is irrelevant.)

If this entire cookbook focuses primarily on preventing malicious inputs, then why do we have a chapter of recipes specifically devoted to this topic?With string validation, we accept all user input as a string, and then accept or reject that string depending on whether it is formatted appropriately.For example, if we ask the user to enter a telephone number, we may want to ensure the data they enter has ten digits.If an error occurs and a stream is set to anything other than goodbit, further stream operations on that stream will be ignored.This condition can be cleared by calling the clear() function.
