Thread: infinite loop

Hello

I have written an infinite loop but i cannot understand wy?
I want to add in the front of a linked list a new struct and after that i want to print it.

Code:

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

typedef int element;

struct cell {
	element e;
	struct cell *p;
};

typedef struct cell* cel;

cel addInFront (cel l, element i);
void writeList (cel l);

int main (void){

	cel list;

	list = NULL;
	
	list = addInFront (list, 5);
	list = addInFront(list, 4);
	writeList (list);
	

	return 0;
}

void writeList (cel l){

	while (l != (cel )NULL){
	printf("\t %d", l->e);
	writeList (l->p);
	}

}



cel addInFront ( cel l, element i){

	cel p;

	p = (cel) malloc (sizeof(struct cell));
	p->e = i;
	p->p = l;
	return p;



}

Check that loop in debugger.

Owk i have updated my code a little

Now i have no longer a infinite loop but my loop doesnt stop at the right time.
Wanted output : 1 2 3 4 5
output : 1 2 3 4 5 5 4 5 5 4 5 5 4 5 5 2 3 4 5 4 5 5 3 4 5 5 4 5 5 stop

I dont see the problem? Because my list is 1 2 3 4 5 NULL and it needs to stop at NULL

Code:

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

typedef int element;

struct cell {
	element e;
	struct cell *p;
};

typedef struct cell* cel;

cel addInFront (cel l, element i);
void writeList (cel l);

int main (void){

	cel list;

	list = (cel) NULL;
	
	list = addInFront (list, 5);
	list = addInFront (list, 4);
	list = addInFront (list, 3);
	list = addInFront (list, 2);
	list = addInFront (list, 1);

	writeList (list);
	

	return 0;
}

void writeList (cel l){

	while (l != (cel)NULL){
		printf("\t %d", l->e);
		l = l->p;
		writeList (l);
	}

}



cel addInFront ( cel l, element i){

	cel p;

	p = (cel) malloc (sizeof(struct cell));
	p->e = i;
	p->p = l;
	return p;



}

Thanx that was indeed the problem

Owk ill use other names next time. Thanx for the hint
