beginner: strange characters returned from array search

[Guest_imported]

I am a beginner and have written some code that searches an array with three rows. it searches for a number and returns a charcter from the array, if there is no entry it returns an *. it works fine for every number i enter except 1 to 6 which return various symbols including a diamond, heart, spade and a couple of smiley faces. can anyone tell me why this is happening.

just a guess, but maybe it is treating the 1-6 as ascii values but then again, why would it not happen for 7-9 and 0?

Try memset on your buffer and set it all to zero

memset(buffer,0,BUFFER_SIZE);

problem was a simple stupid thing i did. the array had ten columns but the search was searching through 100 columns. one too many 0 was the cause of all the problems. lesson learnt: go through code with fine tooth comb
