    linked list HElP

    #include<string.h>
    #include<iostream.h>
    #include<conio.h>
    #include<stdlib.h>
    #define MAX 30

    struct node{
    int age;
    char name[MAX];
    struct node *next;
    };


    /* any ideas why this code want run */

    int main()
    {
    int amount;

    cout<<"How many people to be stored";
    cin>>amount;

    struct node *ptr=(struct node*)malloc(sizeof (struct node));


    strcpy(ptr->name,"ANTHONY");
    cout<<ptr->name;

    ptr->next=(struct node*)malloc(sizeof(struct node));

    free(ptr->next);
    free(ptr);

    return 0;
    }

    /* thanks for the help */

    struct node *next;


    to start, remove the keyword struct from the above line. Not needed in C++.

    You ask how many people should be stored but you have no loop.
    ----So use a for loop for(int i=0; i<size; i++)

    In C++ struct keyword isn't needed.

    If you'd rather adopt a more C++ style (preferred in memory management) use new and delete. --- node *tmp=new node;

    you should at least have a node* head; which always points to the first node in the list.


    ...and this code does run, next time tell us exactly
    what you'd like us to look at
