Eavesdropping attacks are often easy to launch, but most people don't worry about them in their applications.In this case it would be an input that is not an integer.If the cin fails then the input buffer is kept in an error state.
if you had two numbers then you'd verify each was a number, and for the first number read in from the stream you'd multiply it by 10 and add it to the second 1.You have two options here : Let a user type whatever he/she wants into a textbox, validate the input and show him or her an annoying message that he/she has done something wrong.:angry: Or: capture the key before input, check if it's "numeric" and allow only "numerics" to come through.That way, you know the input is correct and you can proceed.:) A decimal point should be correct input, but only once.So, the developer would have declared to store the integer value in say “int a;”. When the user input is accepted using the “cin From the above example, the various functions are used to validate the input like the cin.fail(), cin.ignore(), etc.The various functions of these methods are : cin.fail() - This function returns true when an input failure occurs.
Indeed, most of the soon-to-be-released Secure Programming Cookbook for C and C addresses how to deal with malicious inputs.
