Regarding subtraction of pointers

#1

when we subtract two pointers will they give the no of cells between the two address stored by pointers or the no of elements (variable)

#2

Hello @Namanjain123,

The following program answers your question:

Observation:
1.Subtraction gives the (elements+1) between the two addresses
(or is simply the result of a normal subtraction that you perform you in mathematics).

  1. Why the Output is coming out to be 1?
    address of p1: 0x7ffe24a7ea00
    address of p2: 0x7ffe24a7ea04
    As you know that a single integer variable takes 4 bits space in the memory.
    So,
    Subtraction=0x7ffe24a7ea04 - 0x7ffe24a7ea00=4 (bits)= 1 (for int one element =4 bits)

Hope, this would help.
Give a like, if you are satisfied.
