안녕하세요! 

C언어에서 연결리스트 부분 공부중입니다. 

사람의 나이, 키, 몸무게를 원하는 만큼 넣는것은 함수화 했는데, 출력하는걸 함수화하지 못해서 고민입니다. 

#include <stdio.h>
#include <malloc.h>

typedef struct info
{
    unsigned short int age;
    float height;
    float weight;
    struct info *p_next;

} INFO;

void AddInfo(INFO **qq_head, INFO **qq_tail, unsigned short int age,
             float height, float weight);

/* void PrintfInfo(INFO *qq_head);*/

void main()
{
    INFO *p_head = NULL, *p_tail = NULL, *p;
    unsigned short age;
    float height, weight;
    char count = 0;
    char go = 0;

    while (1)
    {
        printf("input datas (1:go | else:stop) :");
        scanf("%d", &go);
        if (1 == go)
        {

            printf("%dth age :", count + 1);
            scanf("%hu", &age);

            printf("%dth height : ", count + 1);
            scanf("%f", &height);

            printf("%dth weight : ", count + 1);
            scanf("%f", &weight);

            AddInfo(&p_head, &p_tail, age, height, weight);
            count++;
        }
        else
        {
            break;
        }
    }
    count = 0;
    p = p_head;
    while (NULL != p)
    {
        printf("====%dth person====\n", count + 1);
        printf("age : %d\n", p->age);
        printf("height : %5.2f\n", p->height);
        printf("weight : %5.2f\n", p->weight);
        p = p->p_next;
        count++;
    }
    printf("====================\n");
}

void AddInfo(INFO **qq_head, INFO **qq_tail,
             unsigned short int age, float height, float weight)
{
    if (NULL != *qq_head)
    {
        (*qq_tail)->p_next = (INFO *)malloc(sizeof(INFO));
        *qq_tail = (*qq_tail)->p_next;
    }
    else
    {
        *qq_head = (INFO *)malloc(sizeof(INFO));
        *qq_tail = *qq_head;
    }

    (*qq_tail)->age = age;
    (*qq_tail)->height = height;
    (*qq_tail)->weight = weight;
    (*qq_tail)->p_next = NULL;
}

/* void PrintfInfo(INFO *qq_head)
{
    char count = 0;
    while (NULL != qq_head)
    {
        printf("====%dth person====\n", count + 1);
        printf("age : %d\n", qq_head->age);
        printf("height : %5.2f\n", qq_head->height);
        printf("weight : %5.2f\n", qq_head->weight);
        qq_head = qq_head->p_next;
        count++;
    }
    printf("====================\n");
}
*/

이 코드에서 PrintfInfo 함수를 만들어서 하려고 했는데...생각처럼 잘 되지 않았습니다. 

함수를 어떻게 구성해야 좋을까요? 

감사합니다.
