Thread: Index Array simpe task. Need help.

Array is defined by the user (size & members)
1 2 3 4 5 6 7 8 9 10

input k

if index (not the number) can be divided with the k, then that number (not the index is printed).

For example

1 2 3 4 5 6 7 8 9 10 array

k=3

Solution is: 4 7 10

Where is YOUR code?

int main()
{
int brojevi[MAX];
int n, i, k, indikator;




printf("Array input: ");
scanf("%d", &n);
if(n<1 || n>MAX)
{
printf("Error !\n");
return -1;
 }


printf("Insert array elements: ");
 for(i=0;i<n;i++)
scanf("%d", &brojevi[i]);




/printf("Insert number k: ");
scanf("%d", &k);
if(k == 0)
{
printf("Error!\n");
return -1;
}




 indikator = 0;




for(i=0;i<n;i++){
 if(brojevi[i]%k == 0)
{
 indikator = 1;
printf("%d ",i);




 }
}






if(indikator == 0){
 printf("there is no index that can be divided with %d!\n",k);
}


 return 0;
}

you want the program to return the number if the arrays index is devisable by k ie if k was 2 it would return every other element or do you want the index of the integers in the array that are devisable by k

"you want the program to return the number if the arrays index is devisable by k" yes, this is what i want

have a look at the for loop then

I'm looking at it, but don't have the solution yet

well as i said it depends which of the above you wanted to do you have it set for the second option not the first

ok... i agree...help me to set it up for the first option..thanks.

here is a hint

Code:

for(i =0; i <8; i++)
{
         printf("%d", myarray[i])
}

will cycle through the elements of my array and print out to screen the value in each element of my array

Code:

for (i=0;i<7;i++)
{
    printf{"%d",i);
}

will print out the value of i

I already have this in my code... But thanks, anyway...

the point is you are dividing the elements by k not the index

Can you please do the whole code here, so I can test on my side. Thank you.

If the index can be divided by the k (input by the user at the beginning), then I need to printf that element, not the index...

Code:

myarray[i] % 2

divides he element
