c - why is *pp [0] equal to **pp - Stack Overflow That's why when you dereference pp[0] explicitly, with *pp[0], you are dereferencing it effectively twice: First you look at the contents of the address 0x2000, which is 0x1000, and then you dereference that in order to read the memory at 0x1000
Zero to the power of zero - Wikipedia In certain areas of mathematics, such as combinatorics and algebra, 00 is conventionally defined as 1 because this assignment simplifies many formulas and ensures consistency in operations involving exponents

What is the difference between int *p =0; and int *p; *p=0; *p=0; is de-referencing the pointer, accessing the location it points at and attempting to write the value 0 there For this to be ok, the pointer must be set to point at a valid memory location first
Why is that for a pointer *p, p[0] is the address stored at p and p[1 . . . When you evaluate p[1] in your code, you are invoking undefined behavior so your program can do anything It is undefined behavior because p points at n which is just a single integer, not an array of integers So p[0] is n, but p[1] is undefined Basically this is an array overflow bug
O* p = new O [5]; What does p point to? - Stack Overflow Exactly *p and p[0] are the same Here are some neat features you want to know: You can represent an address in memory using either interchangeably: NOTE: I don't think the syntax that allows '1 [p]' is awsome
Equivalence of p [0] and *p for incomplete array types The language specification states that p[0] === *(p + 0) If the size of the pointed-to type is known, that is of course the same as *p, but with unknown size, it would need a special-casing for 0 to work
