     I am having troubles with using gets function. Here is the situation:


      void function() {
       char input[40];

         while (.....)  /* loop begins */
         {
           .. some code

           printf(" enter value %s\n",value);
           gets(value);
           .....

         }  /* end of while */
         
     }

   My problem is the first time I entered the while loop , both printf and gets
statements are not executed.But after that everything is o.k. What I want is 
using a loop to prompt input from the user and get the value. For eaxmple, if 
 there are 5 values to be entered (determined by while loop test ), I will 
prompt 5 times and at the same time get 5 values.


   Is there anything wrong ?

   I have put some more printf statements just before gets, and find that when
I enter the loop for the first time, these print statements are excuted, but
gets is still not executed. It seems that gets sees the EOL charater whenever I
enter the loop for the first time.


     Any advice or help is greatly appreciated . Is there a better and more
reliable  way to do what I need ?


   Thanks in advance.

   If possible, please email to me.
