arrays and random numbers

hi, i am currently trying to get my program to use an array to store 100 random numbers (0-20) or rand % 20, then print those numbers in 5x20 row column format. However i have tried everything possible and not been able to get my program to work. I was hoping someone could give me some help on this one. thankx

Show us what you have so far and where you think you're going wrong.

ok here it is
#include<time.h>
#include<stdlib.h>
#define ROWS = 5
#define COLUMNS = 20

int main (void)

srand(time(NULL));
int array[ROWS][COLUMNS];
int i, j, x
for (i=0; i<100; i++);
array[i]
if (i > 0 && i < 19)
printf("%2d", array[i]);

if (i > 19 && i < 39)
printf("%2d", array[i]);
esle if (i > 39 && i < 59)
printf("%2d", array[i]);
else if (i > 59 && i < 79)
printf("%2d", array[i]);
else if (i > 79 && i < 99)
printf("%2d", array[i]);


that what i have, but i know its wrong

I'll add corrections as I go...

1) Use code tags.

Code:

---

#include<time.h>
#include<stdlib.h>
#define ROWS = 5
#define COLUMNS = 20

/*
    Error #1 - You have no { } around
    the main function.
*/
int main (void)
{
/*
    srand(time(NULL));

    Error #2 - Declare variables before
    calling any functions. This is C, not
    C++.
*/
int array[ROWS][COLUMNS];
int i, j, x

    /*moved to here */
    srand(time(NULL));

/*
    for (i=0; i<100; i++);

    Error #3 - Not technicly an error, but
    not what you want. Your ; at the
    end of the for() function makes your
    function not do anything useful.

    Error #4 - You should really use { }
    whenever you want to create blocks
    of code. Since I don't know where
    you plan on blocking things off, I'll
    assume.

    Error #5 - You shouldn't treat
    multidimensional arrays as single
    dimension arrays. I believe technicly
    they're the same thing, but it's
    generally bad form. As such, this
    should be a nested loop.

    Additionally, you should use your
    define here as a loop counter
    instead of a static number.

    If you want to tread them as a
    single dimensional array here, do
    like so:
*/
    for( i = 0; i < (ROWS*COLUMNS); i++ )
    {
        /*
            This line does nothing. What are you trying to do here?
        */
        array[i]

I'll assume you're trying to assign some random value, but I'll stop here and let you see what you can some up with.

Remember: for every { you need one and only one }

Quzah.
