A pointer variable is declared by giving it a type and a name (e.g. int *ptr) where · the asterisk tells the compiler that the variable named ptr is a pointer variable and

– with c = {‘A’,…, ‘Z’, ‘a’,…, ‘z’, ‘_’ }, d = {0,…,9}, and asterisk “*”

defined which can be accessed using ampersand & operator, which denotes an address in · memory. Consider the following example, which will print the address of the variables defined: ... So you understood what is memory address and how to access it, so base of the concept is over. Now let us see what is a pointer.

November 5, 2025 - Some key points: 1. Pointers store the address of another variable of the same data type. They allow accessing and modifying values using their memory location rather than their name.

A pointer is a variable in C that points to a memory location.
