pointer operators in c
& ==> address operator
* ==> dereference operator
// Example
int a = 1;
int *ptr; // int * defines a pointer variable pointing at an int
ptr = &a; // the address of 'a' is assigned to the pointer
// 'ptr' is now equal to the address of 'a'
// when dereferenced using *, it returns the value at that address
printf("value of a: %d", *ptr); // prints "value of a: 1"how to make pointers in c
datatype *var;
variable var actually holds the address of the data(memory where it is stored)
*var lets you access the data stored at that addressCopyright © 2021 Codeinu
