#inlcude stdio.h
  int main(){
    int arr[5];
    arr++
  }

• Note the arr+ will produce an error lvalue required
• just arr decays to a pointer value, but there is no pointer object. its just a value. arr is just a value.
• hence we need to assign it to something to manipulate the value
• Think about int i = 5. i is a variable (an object that holds things) Also i+1 is a value, u cannot assign i+1 to anything since its a value and not an object
• we cannot say i+1 =5. what we are doing is arr = arr+1. but arr is a value and not a pointer object
• note printf("%p",arr) will give the address of first element
• We can do this ...int* p = arr.... p++. P will keep on incrementing since its an object
