What are void pointers in C?

#include <stdio.h> #include <stdlib.h> #include <string.h> void printBytes(void* arr, int n) { int i; for (i = 0; i < n; i++) { printf("%02x ", ((char*)arr)[i]); } } int main(int argc, char* argv[]) { long long arr[] = { 16, 31, 32, 65 }; printBytes(arr, 4 * sizeof(long long)); return 0; }
