Why do you use a void pointer in a programme?

Answer 1

void is type of pointer that usually means that you can make it point to any data type.

When you make a pointer point to somewhere its data type should match with the place where you want it to point.

When you dont know the data type where it will point to then you can declare a void pointer and make it point to the data type it want.

Answer 2

because void is not return anything every function should have return something void is not return anything so use void

1. pointer: void * is the generic pointer type

2. return value: void means no return value (the default is int)

3. parameter-list: void means no parameters (the default is: unspecified)

Answer 3

void is sort of a "null" type. It can be used to indicate that a function will not return a value or that a pointer has no type applied to it

Answer 4

In C General purpose pointer is called as a void pointer. It doesn't have any data type associated with it. It can store address of any type of variable.
