In C, a void pointer, also known as a generic pointer, is a pointer that can point to any type of data. The void type is a special type that represents the absence of any type. Therefore, a void pointer is a pointer that does not have any type associated with it. Declaring Void Pointer in C:: Here… Read More »
In C, a double pointer is a variable that stores the address of a pointer. It is also known as a pointer-to-pointer. Double pointers are useful when you need to modify the value of a pointer itself, not just the value it points to. Declaring Double Pointer in C: Here is an example of how to declare a… Read More »
In C programming language, a function pointer is a variable that holds the address of a function. It allows us to pass functions as arguments to other functions, store functions in arrays or structures, and call functions indirectly. Declaring Function Pointer in C: To declare a function pointer, you need to specify the return type and the parameter… Read More »
In C programming language, a null pointer is a pointer that has a value of “null”, or “0”. A null pointer is a pointer that does not point to any memory location. It is often used to indicate that a pointer is not currently pointing to a valid memory location. Uses of NULL Pointer in C : Null… Read More »
Pointers are a fundamental concept in the C programming language, which allow direct access to memory locations. A pointer is a variable that holds a memory address, which points to the location of a value in memory. Pointers are used to pass information between functions, dynamically allocate memory, and access data structures. In C, pointers are declared using… Read More »
