    Function to add node between first and last node

    How to make function that can add the new node between fist and last node

    for example

    20 40
    add new value 30

    list 20 30 40

    add new value 50

    list 20 30 50 40

    Code:
    #include <stdio.h>
    
    #include <stdlib.h>
     
     
    struct Node
    {
        int Data;
        struct Node * Next;
    };
     
     
    struct Node * Add_New ( int n, struct Node * Pointer)
    {
     
     
        struct Node *New = malloc(sizeof(*New));
         
         
        // return Pointer;
    }
                      
    int main ()
    {
        
        struct Node * Head = NULL;
        struct Node * Tail = NULL;
        struct Node * Head = malloc(sizeof(*Head));
        struct Node * Tail = malloc(sizeof(*Tail));
        
        
        return 0;
    }

    You've already been shown how to add to the head and tail of a list.
    You therefore ought to be able to at least make an ATTEMPT for yourself now.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    OK, so you understand pictorially what you need to do.

    How about some code to go with it?

    Before you write code, write down detailed step-by-step instructions in English (or whatever language you're most comfortable with) on how you would accomplish the task. Think of it like a recipe: 1. do this, 2. do that, etc. Make sure each step is a simple task that even a simple-minded person can follow (a computer is a simple-minded, but very fast, person). This is often the "hard" part.

    Once you do that, then convert the instructions, line by line, into code. This is the "easy" part.
