Understanding Pointers In C By Yashwant Kanetkar Free Pdf 1763 ◉

int x = 10; int *ptr = &x; printf("%d", *ptr); // prints 10 This code dereferences the pointer ptr and prints the value stored at the memory address it points to, which is the value of x .

A pointer is a variable that stores the memory address of another variable. In other words, a pointer "points to" the location of a variable in memory. int x = 10; int *ptr = &x;

You can initialize a pointer by assigning it the address of a variable using the unary & operator. For example: You can initialize a pointer by assigning it

int *ptr; This declares a pointer variable ptr that can store the memory address of an int variable. For example: To access the value stored at

To declare a pointer, you use the asterisk symbol (*) before the pointer name. For example:

To access the value stored at the memory address pointed to by a pointer, you use the dereference operator (*). For example:
