problem printing output

Mar 10th, 2005

Iam reading in a 4row 3column table.
Iam refering to char_function[4][3] in the following code.This is a part of a larger program. You can neglect all other things and look at char_function
my aim is to print it out

}

why is the output showing only the last column of the table??

You may want to make your tables -- and dummy input --have int type. A character 0 ('\0') is not the same as '0'. Either that, or use '0' and '1' in the char table.

Actually the reason I used 'char' type is because I need to pass this to an already function which takes inout of char type

Either that, or use '0' and '1' in the char table.

This isn't helping me either . The function ain't compiling??

Hi,
I have one more problem now. For the same assignment I need to generate a table of the following king

      0 0 1       1   1   1

and so on.

I've shown it for three variables a , b , c (could be more-say k; k is fixed
and three variables x1, x2, x3(could be more-say upto xN.

I am using arrays to store this as both its dimensions are fixed.
The a,b,c need not always go till (1 1 1).Which means that the number of rows for 3 (k)variables a,b,& c may be less than 8 (2^k)

Plz help me out , The submission is in 15 hrs , so its a bit urgent.

The formatting went wrong.
I've set it right using underscores

a b c.. x1 x1 x3..
0 0 0 __0 _0 _0
0 0 0 __0 _0_ 1
0 0 0 __0 _1 _0
.

0 0 0 __1_ 1_ 1
0 0 1 __0_ 0_ 0
0 0 1 __0_ 0_ 0
.
0 0 1 __1_ 1_ 1

and so on.

I'm still somewhat fuzzy on what it is you're doing, but then I've got a bit of a cold right now.

Is there anything that you could salvage from the following?
