Question

Pointer type void

void* a; // pointer variable with unspecified target type
  • Assignment from any pointer type to void* valid
  • [...] address arithmetic on void* because size of elements unknown
  • Cast to non-void pointer required before usage:
double* d[10];

a = &d;
/*
↓ Derefence double* */
* (double*) a = 3.2;
/*    ↑ Cast a to double*  */
Answer
No
