Examples
  • A wild pointer, which may be used interchangeably with dangling pointer (sense 1):
char* dp;  // dp is immediately dangling as it is uninitialized
  • A pointer to memory that has gone out of scope (sense 2): 
    {
    char* dp = NULL;
    {
        char c;
        dp = &c;
    } 
    // c falls out of scope,
    // so dp is now a dangling pointer
}
