I compiled and ran the program -- I didn't get any runtime errors, but I only entered a couple time zones.
Your program is more than a little confusing. why are you putting just one character at a time in its own array element of query[] ? For example, if I enter 123 <Enter> the program puts query[0] = '1', query[1] = '2' and query[2] = '3'. Then if I enter 234 <Enter> the program puts query[3] = '2', query[4] = '3' and query[5] = '4'. At this point it has
query[0] = '1'
query[1] = '2'
query[2] = '3'
query[3] = '2'
query[4] = '3'
query[5] = '4'
Note that the above contain the ascii values for the numbers I entered, not the binary values. The letter '1' is NOT the same as the number 1. (google for "ascii chart" and you will discover why)
Next you extract the three values from the above array. '1', '2' and '3' are the first thee. Then you attempt to use them as the index into the db array. But db array has a maximum of 9 for each dimension, and you are attempting to access '1' (49 decimal).
You have an array overflow problem -- attemtping to access elements out of bounds. To correct this you need to convert the letters to binary. One way to do that is like this:
Finally, you need to put a break statement at the end of each case.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
Thank you Salem.
I have changed
int db[9][9][9] to int db[10][10][10]
and
for(i=0;i<=100;i++) to for(i=0;i<=99;i++).
That should fix the boundary error.
But still I get the same error at the same point.
Is there anyother way to read the array instead of
zone = db[hundred][ten][one];

Thank You very much Ancient Dragon. That was more than a help for me...
I knew I was using the ascii code instead of decimal value but I totally forgot it during the computation. I will reply after completing the program.
take care.
