What is the definition of a pointer in the C programming language?

Defining a pointer in the C language means creating a variable that stores the memory address of another variable. Pointers can refer to any data type, including basic data types like integers and floats, as well as composite data types like arrays and structures. To declare a pointer variable, you need to specify the data type it points to and use the asterisk symbol “*”. Pointers can retrieve a variable’s address using the address-of operator “&” and access the value of the pointed-to variable using the dereference operator “*”.
