Pointers lay the foundation of C programming, offering direct memory access and manipulation capabilities that are both powerful and complex. As we delve deeper into pointers, we encounter double pointers, an extension of the basic pointer concept. Do
Read: Pointer Rules in C programming language.Declaration of a pointer to pointer (double pointer) in CWhen we declare a pointer variable we need to use dereferencing operator (asterisk character), similarly, to declare pointer to pointer, we need to use two asterisk characters before the ...

While there are 5 primary data types, there are some derived data types too in the C language which are used to store complex data. Derived data types are nothing but primary data types but a little twisted or grouped together like anarray,structure,union,andpointers. ...
Since the vector is holding pointers each of the sort function parameters a and b are pointers to an item* that is in the vector. They are pointers to pointers, Dereferencing a pointer to a pointer would result in an item * pointer, not an item object....

Generally in favor of doing something like this. There's a few aspects I want to highlight Increasing memory: The VM happens to be able to use tagged integers (aka Smis) and compressed pointers. Other backends may not be able to do the same (e.g. compiling to jvm) or would sacrifice...
