Well, to get the reference proper for mupltiple dimensions, the size is involved.

Answer 12

i already know the 2d

Answer 13

The first dimension, you do not need to pass the size of. All others you need to pass the size of. Does not matter if it is 2 or more. You must pass the size of any dimension past the first. Or you deal in pointers an assortment of other ways.

Answer 14

but the question is how can i pass the col to row

Answer 15

statement should i put there

Answer 16

Ah, so you are changing dimensions. You will have to handle it in the function.

Answer 17

and how can i make a statement in the program to make sure no two number have the same of digits

Answer 18

yes

Answer 19

You will need to make your destination array, then have the friction loop through it is the most straightforward way. Pass it the first element of both. OR If you do not need a copy, just need a pointer, you can set it so the elements of the 2nd point to the elements of the first.

Answer 20

what??
you're too advance. :(
explain it step by step please.

Answer 21

i only have less than 30 mins left

Answer 22

In psudocode
arry1[r][c]
arry2[c][r]

for i = 0 to r
for j = 0 to c
arry2[j][i] = arry1[i][j]
next j
next i

A similar method can be done using pointers.

Answer 23

1 array should be used

Answer 24

for example
num[5][2]

Answer 25

Hmmm... not sure if there is a way to easily swap the pointers of the array. If so, that would certainly do it.

Answer 26

hmmm.. :/

Answer 27

Yah, I have swapped the pointers to move rows around or columns around, and there are tons of examples for that. It might be the same thing, but swapping the row and column start pointers.

Answer 28

uhh

Answer 29

swapping to col to col and arranging it from least to greatest

Answer 30

do you have??

Answer 31

You can do that with a sort and swapping the pointers of the columns. The entore column is changed when you swap pointers.

Answer 32

how to input values to first coloum only??

Answer 33

how to pass the values to second value??

Answer 34

what statement should i put on the program??
