scanf leaves out the newline character on the (input) stream, poor getc sees
this newline char before the char you enter and reads it.
It is sometimes a bad idea to use scanf. Always using fgets and then retrieving
the fields by sscanf is a better choice, although it requires a bit more typing.
Before anyone flames me, of course it's possible to use
scanf("%c\n", &c);
and it still has many scanf disadvantages.
