my code is alright, but why it prints me this


-85893460

#include<stdio.h>
#include<stdlib.h>
#define N 20
void main()
{
	int temp,j,i,ar[N];

printf("read 20 nums\n");
for
	(i=1;i<N;i++)
		
		scanf("%d\n",&ar[i]);


		for (i=0;i<N-1;i++){
   		for (j = N-1;j >= i+1;j--){
   			if (ar[j] < ar[j-1])
   			{
     				temp = ar[j];
     				ar[j] = ar[j-1];
     				ar[j-1] = temp;
   			}
}
		}
		for (i=N;i >0;i--){
 	printf("%2d",ar[i]);
	printf("\n");}


	system("pause");
	
}

Because for an array of N elements - indexing starts at 0 and goes up to N-1

well, i changed it but still prints me the same

[guestgulkan]

Did you change it to something like this??

#include<stdio.h>
#include<stdlib.h>
#define N 20
int main()
{
    int temp,j,i,ar[N];

printf("dwse 20 arithmous\n");
for
    (i=0;i<N;i++)
        
    {
     
        scanf("%d",&ar[i]);
    }


        for (i=0;i<N-1;i++)
        {
               for (j = N-1;j >= i+1;j--)
            {
                   if (ar[j] < ar[j-1])
                   {
                     temp = ar[j];
                     ar[j] = ar[j-1];
                     ar[j-1] = temp;
                   }
            }
        }
        
    for (i=N-1;i >=0;i--){
     printf("%2d",ar[i]);
    printf("\n");}
    
 }

it's ok now, i put N-1 at the first for.... thank uou very much!!! ^_^

[Black Pearl]

with that change it will print 19 numbers and no 20 which i want....

[guestgulkan]

oops, I'll recheck


EDIT:
It displays 20 numbers for me (notice my code has i >=0 at the very last for loop - did you put thatchange in?)

[Black Pearl]

i copy-paste your code and now it works.... i can't understand lol


thank you for your time
