If fuction in Linked Lists

[rswest]

hello this its me again. im having trouble using the if function in a linked list. so basically i wanted to count how many nodes contains a character as its element in a linked list. basically it has 5 nodes and all of them has a char element. this is what i had come up with and i am stuck because it seems that the statement for total is not being executed.

#include<stdio.h>
#include<conio.h>
#include<ctype.h>
void main()
{
int total=0;
struct list{
char value;
struct list *next;
}a,b,c,d,e;
struct list *p;
a.value='A';
a.next=&b;
b.value='B';
b.next=&c;
c.value='C';
c.next=&d;
d.value='D';
d.next=&e;
e.value='E';
e.next=NULL;
p=&a;

struct list *rec_ptr;
rec_ptr=p;
printf("The elements are:\n");
while(rec_ptr!=NULL){
printf("\t%c\n",rec_ptr->value);
rec_ptr=rec_ptr->next;}



rec_ptr=p;
while(rec_ptr!=NULL){
if(isalpha(rec_ptr->value)==0){
total=total+1;}
rec_ptr=rec_ptr->next;}

printf("\nTotal Nodes with Character Elements is %d",total);
getch();
}

the output for total is 0, instead of 5. pls anyone can help me?

#include<stdio.h>
#include<ctype.h>
int main()                      //!! fixed
{
  int total = 0;
  struct list {
    char value;
    struct list *next;
  } a, b, c, d, e;
  struct list *p;
  a.value = 'A';
  a.next = &b;
  b.value = 'B';
  b.next = &c;
  c.value = 'C';
  c.next = &d;
  d.value = 'D';
  d.next = &e;
  e.value = 'E';
  e.next = NULL;
  p = &a;

  struct list *rec_ptr;
  rec_ptr = p;
  printf("The elements are:\n");
  while (rec_ptr != NULL) {
    printf("\t%c\n", rec_ptr->value);
    rec_ptr = rec_ptr->next;
  }

  rec_ptr = p;
  while (rec_ptr != NULL) {
    if (isalpha(rec_ptr->value) != 0) { //!! read the manual, what does isalpha() return?
      total = total + 1;
    }
    rec_ptr = rec_ptr->next;
  }

  printf("\nTotal Nodes with Character Elements is %d", total);
  return 0;                     //!! fixed
}

Some things (like strcmp) return 0 when things match.
Other things (like isalpha) return 0 when things DO NOT match.

thank you salem. sorry for the late reply. your links that you shared help a lot. im now on my final term in programming c. i was given a proect to make a hangman game in C. i have seen a few here on the site. if i encounter some problems ( im pretty sure i will! ) ill post it here and i hope you will help me again. you are very kind salem. thank you
