A void pointer can be really useful if the programmer is not sure about the data type of data inputted by the end user. 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 ...

C++ - how to cast void* to float** in c, a void pointer to, &Joe is the address of that pointer, so it is a pointer to Joe, which is a pointer that points to something we don't know (void **). You cast that pointer to float* and that gives a pointer to Joe, but the c...
void *v_ptr; C Copy This declaration uses the C-reserved word void for specifying the type of pointer. Pointers declared in this manner do not have any type associated with them and can contain the address of any type of variable (int, char, float). Valid C statements in Void Pointer ...
1:In C,void*can be used as a return value and function parameter but in C++ you must have a specific data type of pointer. For example: In C, the code is given below: #include <stdio.h> #include <stdlib.h> void*add_numbers(inta,intb){ ...
6.5.6-2: For addition, either both operands shall have arithmetic type, or one operand shall be a pointer to an object type and the other shall have integer type. So, the question here is whether void* is a pointer to an "object type", or equivalently, whether void is an "object ty...
