Thread: linked list not working :(

this program reads from standard input, storing each character into a linked list, then prints out characters stored in the list, but with space character changed into underscore "_".

Code:

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

typedef struct node nodeType;

struct node
{
  char name;
  nodeType *next;
};

nodeType*
chinsert(nodeType* ptr,char c)
{
  nodeType *p;

  nodeType *new = (nodeType *)(malloc(sizeof(struct node)));
  new->name = c;
  new->next = NULL;

  if(ptr==NULL)
    return new;
  
  else
  {
    for(p=ptr; p->next!=NULL; p=p->next);
    
    p->next= new;

    return ptr;
  }
}

void
prnList(nodeType *ptr)
{
  nodeType *n = ptr;

  printf("\n");
  
  while(n != NULL)
  {
    printf("%c",n->name);
    n = n->next;
  }
  
  printf("\n");
  
}

void
prn(nodeType *ptr)
{
  nodeType *n = ptr;

  while(n != NULL)
  {
    if(n->name == ' ')
      printf("%c",n->name='_');

    else
      printf("%c",n->name);

    n = n->next;
  }

  printf("\n");

}

void
cleanUp(nodeType *ptr)
{
  nodeType *n;

  while(ptr->next != NULL)
  {
 
    n = ptr->next;
    ptr->next = n->next;
    free(n);
  }

   n = ptr;
   free(n);
}

int
main(int argc, char *argv[])
{
  char c;
  nodeType *ptr = NULL;

  while((c=getchar())!=EOF)
  {
    ptr = chinsert(ptr,c);
  }

  prnList(ptr);
  prn(ptr);
  cleanUp(ptr);

  return 0;
}

can anyone see why this doesnt work?

do i need a printf in the main?

my mistake, it works
