Thread: delete a node from linked list problem

Code:

arxeio=first;         s=0;
         while(arxeio!=NULL)
         {
            if (arxeio->aStudent->idNumber==iddel)
            {
            printf("erasing id %d",arxeio->aStudent->idNumber);
    if(first->aStudent->idNumber==iddel)     /* first node to be deleted) */
    {
        temp1 = first->next;  
        free(first);        
        first= temp1; 
        s=1;    
    }


              }
              
                   
           if (arxeio->next->aStudent->idNumber==iddel)
            {
            if (arxeio->next!=NULL)   
            {
              temp1=arxeio->next->next;
              free(arxeio->next);
              arxeio->next=temp1;
              }                                              
            s=1;
            }


            arxeio=arxeio->next;
            } 
            if (s!=1)
            { 
                     printf("error! wrong id");
            }

the list contains the following nodes
first:
alex
4598
------
john
2245
------
tom
4445

if i ask to delete the id 4445 my program works just fine,if i ask to delete any other node the program stops.any idea why is this happening?

break was the issue after all,i wrote one break in every if loop an the problem is solved.So now the question is why "break"?

Fix your indentation, your code looks horrible. Bad formatting/indentation means it's easy to make mistakes and hard to find or fix them. And it means nobody here will want to help you.

Oh, and there is no such thing as an "if loop", so I have no idea where you put the break statements. Please post your new code, properly indented, and with the break statements.
