Hi..i'm very new to thic C++ programming..in doing my assignment i face some difficulties..f irst
1) i use 2 dimension of array e.g," 1 columns and 5 numbers under each column"...and i ask the user the fill the numbers
2)Then, i want display back all the numbers that have been stored but it just display the last number in the column..i don't have any idea to make it display all the inputs..
Here, the programme that i've written so far...if anybody can help me and i do really appreciate that...

#include <stdio.h>

}
when you print the matrix you only print the last element - you need another loop, e.g. -
printf("the matrice is...");
-
do {
-
for(num=0; num<NUM-1; num++)
-
printf("\n %d\n\t", results[col][num]);
-
++col;
-
}while (col < COL);
-
for simple loops it is usually easier to use a for() loop to do the same thing as a while(), e.g. -
printf("the matrice is...");
-
for(col =0; col<COL; col++)
-
for(num=0;num<NUM-1;num++)
-
printf("\n %d\n\t", results[col][num]);
-
you could change your input to use a for()
why do you have 6 elements in the array and only use 5?
oh thanx a lot...hurm i think i juz make it too complicated, act i can juz simply define NUM 5 and num<5 as it starts from num=0...
anyway i can now display all the elements but how to make it really looks like the arranggement of a matrix...
for e.g if i have 2 columns
first column
1
2
2nd column
3
4
but how display the whole matrix like this?
1 3
2 4

I have a large form that is generated dynamically in a jsp using xml / xslt. So, to

to "display:", or hidden with "display:none". This gives the illusion that the person
filling out the form is switching from page to page...without the overhead of extra

Hi
When toggling an element on and off by setting its display property via
DOM access, display:none is valid for all kinds of elements, but I can't
find anything about a generic value for toggling on again.
Furthermore, UAs do not recognize the same values. To make a table row
visible, IE wants display:block while FF wants display:table-row.
Am I missing something? I am looking for something like display:normal

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
