Above is link of my code
How here value of a changed to 1 ?
what p[1], p[0] point to in non array variables?
Please explain
Pointer Arithmetic
a is pointing to p array
a points to first index
so if u print a
then value at index 0 of p is printed which is 1
But here p is pointing to a.
NOT a is pointing to p
by add i mean address of a is 100 ( supposed)
now since p is pointing to the memory location of a
and then u update the value at p[0] which is actually pointing to memory location of a so indirectly the value of a is getting updated
So p[1] does not make sense. right?
in above code i have used typecasting of same code. Now can you please explain output !
How a is incremented by 1?
probably no because, i am not even able to access it using *(p+1)
or assinging it to another pointer
it is giving runtime error if u access p+1
for the updated case code, i request u to go through the below article, its nicely explained
