Void is typically used in several different contexts. Functions that do not return a value. Most commonly, void is used to indicate that a function does not return a value: void writeValue(int x) // void here means no return value { .

There are 3 basic ways that void is used: Function argument: int myFunc (void) -- the function takes nothing. Function return value: void myFunc (int) -- the function returns nothing. Generic data pointer: void* data -- 'data' is a pointer to data of unknown type, and cannot be dereferenced.

void. What is void in C programming? It means “no type”, “no value” or “no parameters”, depending on the context. We use it to indicate that: a function does not return value. a function does not accept parameters. a pointer does not have a specific type and could point to different types. A void function does not return a value.

This operator allows evaluating expressions that produce a value into places where an expression that evaluates to undefined is desired. The void operator is often used merely to obtain the undefined primitive value, usually using void (0) (which is equivalent to void 0).

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“. Syntax of Void Pointer in C++ void* ptr_name;

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* ptr {}; // ptr is a void pointer. A void pointer can point to objects of any data type:
