#### Let's call this one labscan.c

#### Write a program that reads pairs of numbers and prints them out.
#### Maybe something like this Python program. (Enter one number per line.)
while True:
    x = int(input())
    y = int(input())
    print "{0}*{1} is {2}".format(x, y, x*y)

#### Call your program labprint.c
#### OK... Here it is.
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
  while(1) {
    int x, y ;
    scanf("%d %d", &x, &y) ;
    printf("%4d * %4d = %8d\n", x, y, x*y) ;
  }
  return 0 ;
}

#### Using the fact that scanf returns the number of arguments read,
#### rewrite your program to end when the "user" types EOT (aka ^D)



#### Replace the call scanf("%d %d", &x, &y)  with scanf("%d %d", p, q)
#### Now modify your program so that it works.
#### You will need to declare a couple of pointer variables.
#### By the way, this is a very silly thing to do.


#### Pretend you're a FORTRAN programmer and integers are "punched" in
#### six digit fields (such as 000004001000). How do you handle that?

#### What if they are separated by commas (such as 4,1000)?
