Scanf function parameter Mismatch

In Linux, we often encounter the following problems:Code:

While (1) <br/>{< br/> scanf ("% d", x); <br/> printf ("% d", X ); <br/>}
 

If the input content is not an integer, for example, if a letter is entered, scanf will not read the content in the input cache, and the result will automatically fall into an infinite loop.

The solution is to refresh the input cache. The common solution in Linux is as follows:While (1) <br/>{< br/> scanf ("% d", & X ); <br/>/* "eat" the remaining data in the input stream through the while loop */<br/> while (C = getchar ())! = '/N' & C! = EOF); <br/> printf ("% d/N", x); <br/>}

In this way, you can continue normal input without matching.
