Thread: Linked List program help

I don't understand linked list very well and am a bit confused. I searched and tried to learn how to use them correctly on the internet, but I doubt this is correct.

I'm trying to get the program to make a linked list with, First name, last name, SSN, and DOB.

Any feedback on what to do, or help with code would be greatly appreciated.

if you know of a good tutorial on linked list, because I want to learn and understand them in greater depth, please share it with me.

thanks in advanced

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
main()
{
      struct student
      { 
        char firstName[20];
        char lastName[20];
        int socialSecurity;
        int dob;
        student * next;
      }newStudent; structures
      
      student * temp;
      student * start;
      student * end;
      
      temp = new student;
      temp ->lastName[0] = 'Donald';
      temp ->firstName[0] = 'Mat';
      temp -> socialSecurity = 354-56-5632;
      temp -> dob = 10-18-87;
      temp ->next = NULL;
      
      start = temp;
      end = temp;
      temp -> next = start;
          
      temp = new student;
      temp ->lastName[0] = 'Brown';
      temp ->firstName[0] = 'Tom';
      temp -> socialSecurity = 352-33-5111;
      temp -> dob = 12-25-83;

      temp ->next = NULL;
      
      end ->next = temp;
          
          for(student *s = start; s; s = s->next)
            printf("name %s\n", s->lastName);
      
      system("pause");  
      
}

You need to decide if this is a C or C++ program. The "new" is a C++ keyword not available in C. In C you would use malloc and free for dynamically allocating memory. Also your structure usage is incorrect for C. See this link for information on how to use structures in C.

Hey dob should be character or structure same Socialsecurity and the way u r initializing the firstname and last name is also not proper. You can use pointer to character to store the names..

I'm going between C and C++ and this is C++. Sorry for posting in the wrong place.

If this is C++ you should stop using the C-strings and use std::string instead. And as already pointed out all the fields should really be strings.
