[ASSIGNMENT] Lets generate this pattern!!

Question

var array=[1,2,3,4,5,6,7,8, 9];
//pattern
123
234
345
456
567
678
789
891
912
123 ....to infinity
the pattern itself is easy,the problem is the pattern restarting after its reached the end.i need this for a web code,thanks
Note::it should work with an array of any length or elements.Thanks!!😄
non web codes might help too

Just do this :
""+arr[i%length]+arr[(i+1)%length]+arr[(i+2)%length]

Answer 3

to get the next value you can use :
( current modulo number ) + offset
in your case it is : ( current % 9 ) + 1
to reach the correct next value

first part of problem as David told with modulo then

to solve the situation when reached at end of array, concat the ending array part and starting array part in a single arrray , it ll happen when

#include<iostream>
using namespace std;
int main()
{
int arr[]={1,2,3,4,5,6,7,8,9};
int i,j=0,k=0;
while(k<20)
{

for(i=1;i<=3;i++)
{
if(j==10)
{
j==1;
}
cout<<arr[j];
j++;
}
if(j==10)
{
j%9+1;
}
j=j-2;
cout<<"\n";

k++;
}
