Explanation / Answer

#include<stdio.h>
#include<stdlib.h>

struct node {

    char *name;
    char *artist;
    int num_songs;
    struct node *next;
};

struct node *add(struct node *n, char *nm, char *art, int num){

    struct node *temp, *ptr;
    temp = (struct node *)malloc(sizeof(struct node));
    temp->name = (char *)malloc(sizeof(char)*20);
    temp->artist = (char *)malloc(sizeof(char)*20);
    temp->name = nm;
    temp->artist = art;
    temp->num_songs = num;
    temp->next = NULL;

    if (n == NULL){
        n = temp;
       
    }
    else {
       ptr = n;
       while (ptr->next != NULL)
            ptr = ptr->next;
       ptr->next = temp;
     
    }
    return n;

}

void display(struct node *n){

    struct node *ptr;
    ptr = n;
    while (ptr != NULL){
        printf("--------------------------- ");
        printf("Name:%s ", ptr->name);
        printf("Artist:%s ", ptr->artist);
        printf("Number of songs:%d ", ptr->num_songs);
        ptr = ptr->next;
    }
    printf(" ");
}

int main(){

    struct node *start;
    start = NULL;

    start = add(start,"Name1", "Artist1", 5);
    start = add(start,"Name2", "Artist2", 7);
    start = add(start,"Name3", "Artist3", 10);
   
    display(start);
    return 0;
}
