Introduction:-
A pointer is a special variable that is used to store the address of some other variable. A pointer can be used to store the address of a single variable, array variable, structure, union, or even a pointer.
The concept of pointers:-
Every variable is stored in the memory, and each memory location has a numeric address. The declaration of the variable int a = 5; Here a is the name of the variable, the value of the variable is 5 while the address of the variable is 100 (assumed).
The declaration of the variable tells the compiler to :-
1. Reserve space in the memory to hold the integer value.
2. Associates the name “a” with this memory location.
3. Stores the value 5 at this location.
Pointers and the indirection operator:-
The two fundamental operators used with the pointers are:
'); var s = document.createElement('script'); s.type = 'text/javascript'; s.async = true; s.src = 'https://ad.admitad.com/shuffle/289c251618/'+subid_block+'?inject_to='+injectTo; var x = document.getElementsByTagName('script')[0]; x.parentNode.insertBefore(s, x); })();
