Given two Arrays, arri and arr2, write a C++ function to check if arr2 is a sub array of arri. For Example: if arri {1, 2, 3, 4) and arr2 = {2, 3) then arr2 is a sub of arr1 while if arr2= {2, 4) then arr2 is not a sum of arri. Note: You must use the following header: bool is Sub(int arri[],int arr2[])
