/* This example illustrates the problem mentioned about scanf, i.e., that when it is
matching input to %d or %f, it ends the scan when it sees input that can't be part of
the number it is reading. However, it does not consume that input. So when the shareprice input
is read, the newline character is left unconsumed. Then that newline character is the next
thing read in the next scanf. So stockcode2 gets assigned the newline character, which is
not what one would want.  */
