    Reason: when we are doing p[i] it is actually equall to *(p+i) ,
    similarly when we are doing &p[i] it is equal to (p+i) so giving address,
    when we do &((&p[a])[b]) is it equall to (p+a+b) , p=0 so 0+a+b = a+b ,
    i have used integer type casting because pointer p was of character type
