How do I prevent a runaway input loop when I request a number but the user enters a non-number?

Question

I need to know how to make my cin statement not appear to \'remove\' itself if you input the wrong type. The code is here:

int mathOperator()
{
  using names         


        

Answer 1

I agree that a char is just as handy, since you can always cast to int, to answer your question as to why this is happening, when a cin input is exected as an int but a char is entered, the input is kept in the input stream for the duration of the loop, which is why it seems to "disappear."
