Help find out what's wrong with

readPuzzle and printPuzzle Requires works. SetOfSmallInts is a set containing {1,2,3,4,5,6,7,8,9} or any combination of those numbers singletonets (S) Store a single number in a set. No matter what input I run on this program, I only use 1 I even if all input '-' output is 81 1. Any suggestions? To create an array of puzzle types in the main SetofSmallInts [9] [9] .

All you need is a scanf ("% c", & Amp; n)

is also a character

such as

  else if (n == 1 || n == 2 || n == 3 || n == 4 || n == 5 || n == 6 || n == 7 || n == 8 || n = 9 9)  

to n == '1' etc etc

or else if (n> gt; = '1' & amp; amp; ; & Amp; N & lt; = '9')

Then you may

  p [i] [j] = singleton set (n - '0') will be required;
