printing problem

i think the logic in my program is alright but the only poblem im having is saving the values throughout the process and outputting it at once. Its supposed to be a string that is constantly updated, in this case called rule. it keeps giving me a segmentationaly fault for some reaosn and ive not been able to figureout why.
any help and alternative methods are appreciated!

the segmentationaly error occours once it reads the 1st r_o value in the second for loop.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
#include <math.h>


int main(int argc, char **argv)
{
    int width = 0;
    int height = 0;
    double r_o = 0;
    double g_o = 0;
    double b_o = 0;
    double r_e = 255;
    double g_e = 0;
    double b_e = 0;
    int r_number = 0;
    int g_number = 0;
    int b_number = 0;
    int counter = 0;
    int Rule =0;
    int rule[Rule];
    int p_count = 0;
    
   
    scanf("&#37;d", &width);
    scanf("%d", &height);

    int i = 0;
    int j = 0;

    for (i = 0; i<= width; i++){
                    
        rule[Rule]='[';
                    Rule++;
	for (j = 0; j<=height; j++) {
            
            scanf("%lf", &r_o);
            counter = 0;
            if (r_o < r_e) {
                r_number = r_e - r_o;
                
                    while(counter<=r_number) {
                    rule[Rule]='R';
                    Rule++;
                    counter++;
                }

            } else if (r_o > r_e) {
                r_number = r_o - r_e;
                while (counter <= r_number) {
                    rule[Rule]='r';
                    Rule++;
                    counter++;
                }
            }

	    scanf("%lf", &g_o);
            counter = 0;
            if (g_o < g_e) {
                g_number = g_e - g_o;
                while (counter <= g_number) {
                     rule[Rule]='G';
                    Rule++;
                    counter++;
                }

            } else if (g_o > g_e) {
                g_number = g_o - g_e;
                while (counter <= g_number) {
                    rule[Rule]='g';
                    Rule++;
                    counter++;
                }
            }	

	    scanf("%lf", &b_o);
            counter =0;
            if (b_o < b_e) {
                b_number = b_e - b_o;
                while (counter <= b_number) {
                    rule[Rule]='B';
                    Rule++;
                    counter++;
                }

            } else if (b_o > b_e) {
                b_number = b_o - b_e;
                while (counter <= b_number) {
                    rule[Rule]='b';
                    Rule++;
                    counter++;
                }
            }

    rule[Rule]='F';
                    Rule++;
        }
 rule[Rule]=']';
                    Rule++;
rule[Rule]='+';
                    Rule++;
rule[Rule]='f';
                    Rule++;
rule[Rule]='-';
                    Rule++;
    }


   for(p_count = 0; p_count <=Rule;p_count++) {
      printf("%c",rule[p_counter]);
    }


 return(0);
}

dont be harsh..im fairly new to this stuff lol

This isn't even legal C.
What you've basically got here is
int rule[0];
which simply has no space for storing anything.

Perhaps
int rule[1000];
and make sure that Rule keeps within bounds.

Try flushing stdout here:

Code:

   for(p_count = 0; p_count <=Rule;p_count++) {
   {
      printf("&#37;c",rule[p_counter]);
      fflush(stdout);
   }

thanks guys. it seems to be working with a few tweaks.
also,
say i want to declare an array size of (500X400X3X6) ie large array size it doesnt let me do this the normal way and when i compile it it gives me an error saying array size too big>?
question being: how do i declare very large arrays?

Try using malloc() to dynamically allocate memory. Check return value.
