What is the use of unsigned char pointers? I have seen it at many places that pointer is type cast to pointer to unsigned char . Why do we do so? We receive a pointer to int and then type cast it to unsigned char* . But if we try to print element in that array using cout it does not print anything. Why? I do not understand. I am new to C++. EDIT Sample Code Below int Stash::add(void* element) { if(next >= quantity) // Enough space left? inflate(increment); // Copy element into storage, starting at next empty space: int startBytes = next * size; unsigned char* e = (unsigned char*)element; for(int i = 0; i < size; i++) storage[startBytes + i] = e[i]; next++; return(next - 1); // Index number }
