Thread: simple program 2

ok below is a sample program I used to
multiple 2 numbers the numbers can be
more than 1 digit,. I know its long winded
and the functions are not needed but I was
just trying to get to grips with different
things as im used to delphi. the program
has one problem when it asks if you want
to try again the program ends and does not
wait for input, im guessing there is still
something in the input buffer. Can you
have a look and tell me how this could be
fixed and if theres anyhting else I should
have done different? code exmaples would be
great.

Thanks.

Code:

 
#include <stdio.h>

int  intAnswr(int,int);
char chrRpt (int);

int main ()

{
   int intN1,intN2;
   int intFst;

   intN1 = 0;
   intN2 = 0;
   intFst = 0;

   while (chrRpt(intFst) == 'Y')
   {
      intFst = 1;
      printf ("\nEnter First No.  : ");
      scanf ("%d",&intN1);
      printf ("Enter Second No. : ");
      scanf ("%d",&intN2);
      printf ("\n%d * %d = %d\n",intN1,intN2,intAnswr(intN1,intN2));
   }
}


char chrRpt(int intRun)
{
char chrTmp='Y';
   if (intRun != 0)
   {
      printf("Try Again? Y/N");
      scanf ("%c",&chrTmp);
   }
   return (chrTmp);   
}


int intAnswr(int n1,int n2)
{
   return(n1 * n2);
}

use:

Code:

fgetc(stdin,mychar);

instead of scanf

-LC

i dunno, just because, no particular reason. I just like it. I mean how cool is that 'f' in front. You can post it on a C++ board and the guys who don't know C would be like, "oh, whats that?" LOL

j/k

or you could just use fflush(stdin) (freaky dissonant piano music plays and lightning strikes) Just kidding, DONT DO THIS.

use whatever u want, I just like fgetc()

PS: See C_Refrence_Card in my Signature

-LC

also sorry to sound stupid but can some explain this

while ( getchar() != '\n' );

is this clearing out the buffer? im guess getchar is taking the contents ofthe input buffer one by one until it reaches the end?

also as its while with a semi colon at the end does that mean the next statement is not included in the loop?
