Jan 9, 2024 · A void pointer is a pointer that has no associated data type with it. A void pointer can hold an address of any type and can be typecasted to any type. Example of Void Pointer in C
Jan 17, 2024 · In C++, a void pointer is a pointer that is declared using the ‘ void ‘ keyword (void*). It is different from regular pointers it is used to point to data of no specified data type. It can point to any type of data so it is also called a “ Generic Pointer “.
Jan 9, 2024 · Void Pointer in C. Void pointer is a specific pointer type – void * – a pointer that points to some data location in storage, which doesn’t have any specific type. Void refers to the type. Basically, the type of data that it points to can be any. Any pointer type is convertible to a void pointer hence it can point to any value.
Sep 29, 2023 · The void pointer, also known as the generic pointer, is a special type of pointer that can be pointed at objects of any data type! A void pointer is declared like a normal pointer, using the void keyword as the pointer’s type:
void Pointer in C. A void pointer in C is a type of pointer that is not associated with any data type. A void pointer can hold an address of any type and can be typecasted to any type. They are also called general-purpose or generic pointers.
Dec 16, 2011 · The void pointer, also known as the generic pointer, is a special type of pointer that can be pointed at objects of any data type! A void pointer is declared like a normal pointer, using the void keyword as the pointer’s type:
The functions for dynamic memory allocation (see Dynamic Memory Allocation) use type void * to refer to blocks of memory, regardless of what sort of data the program stores in those blocks. With type void *, you can pass the pointer around and test whether it is null.
In such situations, we can use the pointer to void (void pointers) in C++. For example, // void pointer void *ptr; double d = 9.0; // valid code ptr = &d; The void pointer is a generic pointer that is used when we don't know the data type of the variable that the pointer points to.
In such a case the programmer can use a void pointer to point to the location of the unknown data type. The program can be set in such a way to ask the user to inform the type of data and type casting can be performed according to the information inputted by the user. A code snippet is given below.
Jun 4, 2023 · Void pointer is a generic pointer that has no relation to any data type. It can store the address of a variable of any type and can be easily type-casted to any data type. The declaration of void pointer is similar to a normal pointer, but the void keyword is used while declaring a void pointer. Syntax -: void *pointer_name; Example -: void *ptr;
