What is returned from myFun  when it is passed {1, 4, 4, 6}?

What is the implementation of each instruction located in the main function of the following code? This is a sample program, i am trying to teach myself linked list and am having trouble  ------------------------------------------------------------------------------- #include <iostream>#include <string> /*** node* * A node class used to make a linked list structure*/ template<typename type>struct node {node() : data(), next(nullptr) {}node(const type & value, node * link = nullptr) : data(value), next(link) {}type data;node * next;}; /*** print_list* @param list - the linked-list to print out* * Free function that prints out a linked-list space separated.* Templated so works with any node.* Use this for testing your code.*/ template<typename type>void print_list(node<type> * list) { for(node<type> * current = list; current != nullptr; current = current->next) {std::cout << current->data << ' ';}std::cout << '\n';} /***…

Could I get an example of a program writen in C that uses qsort() to sort its command line vector argv by the length of the strings? This is part of my first project and I don't understand pointers very well. If you have a video on how it is done that would work too. I looked at the meterial provided to me and I still cant rap my head around it. If this is to big of a question if you could baby step me through how pointers work that would be a great help. Thank you

OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. Make sure to have the following methods below:    -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction -Command mul refers to integer multiplication -Command div refers to integer division -Command rem refers to the remainder of integer division -Command neg is to calculate the negation of an integer -Command swap interchanges the top two elements in the stack, meaning that the…
