大体思路是这样，没有考虑容错

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

#define person_info_file "person_info.txt"
#define NAME_LENGTH 16
#define PROVINCE_LENGTH 16
#define DATE_LENGTH 32
#define SEX_LENGTH 8
#define EDUCATION_LEVEL_LENGTH 32
#define PERSON_COUNT 32
#define ONE_LINE_LENGTH 1024
#define CONTENT_STRING_LENGTH 32
typedef struct TreeNode
{
    char name[NAME_LENGTH];
    char province[PROVINCE_LENGTH];
    char birthday[DATE_LENGTH];
    char deathday[DATE_LENGTH];
    char sex[SEX_LENGTH];
    uint8_t height;
    char education[EDUCATION_LEVEL_LENGTH];
    uint8_t age;
} person_info_t;

//通过依次查找空格(' ')的位置，从而获取对应字段，填充person_info
void set_person_info(const char *str, person_info_t *person_info)
{
    char content[CONTENT_STRING_LENGTH] = {0};
    char *start = NULL;
    char *end = NULL;

    start = str;
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    strcpy(person_info->name, content);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    strcpy(person_info->province, content);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    strcpy(person_info->birthday, content);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    strcpy(person_info->deathday, content);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    strcpy(person_info->sex, content);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    person_info->height = strtol(content, NULL, 10);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    strcpy(person_info->education, content);

    start = end + 1;
    while (*start == ' ')
    {
        start++;
    }
    end = strchr(start, ' ');
    memcpy(content, start, end - start);
    person_info->age = strtol(content, NULL, 10);
}

int main()
{
    uint8_t i = 0;
    person_info_t person_infos[PERSON_COUNT];
    char buff[ONE_LINE_LENGTH] = {0};
    int fp = fopen(person_info_file, "r");

    while (fgets(buff, ONE_LINE_LENGTH - 1, fp) != NULL)
    {
        set_person_info(buff, &person_infos[i]);
        i++;
    }
    return 0;
