title: Scanf and While Loop not waiting for user input
body: <p>I want this code to ask a user to put in a year and then tell them if it is a leap year. Then ask them if they would like to check another year. At the moment, it asks the first question okay and gives back the answer. </p>
  
  <p>The program then prints out the next question but doesn't wait for input and exits the while loop. I have looked for a resolution on the other posts and thought I maybe had it but it keeps doing the same thing. Could anyone help with what was supposed to be a program to write up and pass some time which has now become a headache? I've written many more complex programs and this one has me frustrated. I hope I've been clear. Much appreciated!    </p>
  
  <pre><code>//Check if the year is a leap year
  #include &lt;stdio.h&gt;
  
  #define YES 1
  #define NO 0
  
  void leapyear()
  {
      int year;
      printf("Enter a year: \n");
      scanf("%i", &amp;year);
      int x = year % 4;
      int answer;
      if (x == 0)
      {
          answer = YES;
      }
      else
      {
          answer = NO;
      }
      if (answer == YES)
      {
          printf("The year %i is a leap year.\n", year);          
      }
      else
          printf("The year %i is not a leap year.\n", year);
  }
  
  int main (void)
  {
      char again;
      printf("Would you like to check if a year is a leap year? y or n\n");
      scanf("%c", &amp;again);
      while(again == 'y')
      {
          leapyear();
          printf("Would you like to check if a year is a leap year? y or   n\n");
          scanf("%c", &amp;again);
      }
      return 0;
  }
