Pointer to traverse an array usage

int ARR [ . 5 ] = { . 1 , 2 , . 3 , . 4 , . 5 };
 int * P = ARR;
 for ( int I = 0 ; I < . 5 ; I ++ ) 
{ 
    ARR [I] = represents an array element 0
     * (P + i) = a pointer indicating the element 0
     * P + I = a pointer indicating the element 0 
    P [I] = represents a pointer element 0 
    P ++ = expressed pointer element 0
