Question

我有一个像这样的文本文件：

Naruto, Wind, 85, 48, 35, 63
Neji, Fire, 57, 53, 81, 45
Gaara, Earth, 73, 47, 96, 50
Sasuke, Fire, 68, 82, 72, 41
Kankurou, Water, 59, 42, 97, 60

我有我的结构

typedef struct ninja{ 
    char* name; 
    char* element; 
    int ninjutsu ; 
    int genjutsu ; 
    int taijutsu ; 
    int defesa ; 
} Ninja ;

我需要读取文本文件，并使用此结构将其直接加载到内存中。我应该创建一些数组，按char将信息存储在char中，然后转换类型（当为int时）然后加载吗？。

void file(){
    FILE *file = fopen("ninjas.txt", "r");
    int c;
    if (file) {

       while ((c = getc(file)) != ','){
          putchar(c);
       }
       while ((c = getc(file)) != ','){
          putchar(c);
       }
       while ((c = getc(file)) != ','){
          putchar(c);
       }
       while ((c = getc(file)) != ','){
          putchar(c);
       }
       while ((c = getc(file)) != ','){
          putchar(c);
       }
       while ((c = getc(file)) != '\n'){
          putchar(c);
       }

   fclose(file);
}

}

我想我明白了！你们觉得还好吗？

void file(){
    FILE *file = fopen("ninjas.txt", "r");
    char str[60];
    const char s[3] = ", ";
    char *token;
    if (file) {
        while (fgets (str, 60, file) != NULL){
           token = strtok(str, s);
           printf( " %s\n", token );
           token = strtok(NULL, s);
           printf( " %s\n", token );
           token = strtok(NULL, s);
           printf( " %s\n", token );
           token = strtok(NULL, s);
           printf( " %s\n", token );
          token = strtok(NULL, s);
          printf( " %s\n", token );
          token = strtok(NULL, s);
          printf( " %s\n", token );
      }
  fclose(file);
  }

}

您的问题可能是从文件读取后解析输入的。我写了一个可以在我的系统中完美运行的解决方案（使用gcc的Ubantu）。我使用fgets（）方法读取一行，然后使用strtok（）函数对其进行解析。

这是代码。

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

#define MAX_RECORD 100

    #define MAX_LINE 200
    typedef struct ninja{ 
        char* name; 
        char* element; 
        int ninjutsu ; 
        int genjutsu ; 
        int taijutsu ; 
        int defesa ; 
    } Ninja ;

        int main(int argc,char** argv){

                FILE *fptr=fopen("input.txt","r");
                if(fptr==NULL){
                printf("Error in openning file\n");
                return 1;
                }
                Ninja ninjas[MAX_RECORD];
                int total_record=0;
                char line_buffer[MAX_LINE];
                while(total_record< MAX_RECORD && fgets(line_buffer,MAX_LINE,fptr)!=NULL)
                {
                        char *curr_record=NULL;
                        curr_record=strtok(line_buffer,",");
                        ninjas[total_record].name=(char *)malloc(sizeof(char)*50);
                        strcpy(ninjas[total_record].name,curr_record);
                        curr_record=strtok(NULL,",");
                        ninjas[total_record].element=(char *)malloc(sizeof(char)*50);
                        strcpy(ninjas[total_record].element,curr_record);
                        curr_record=strtok(NULL,",");
                        ninjas[total_record].ninjutsu=atoi(curr_record);
                        curr_record=strtok(NULL,",");
                        ninjas[total_record].genjutsu=atoi(curr_record);
                        curr_record=strtok(NULL,",");
                        ninjas[total_record].taijutsu=atoi(curr_record);
                        curr_record=strtok(NULL,",");
                        ninjas[total_record].defesa=atoi(curr_record);
                        total_record++;
                }
                for(int i=0;i<total_record;i++)
                {
                        printf("%s %s %d %d %d %d",ninjas[i].name,ninjas[i].element,ninjas[i].ninjutsu,ninjas[i].genjutsu,ninjas[i].taijutsu,ni$
                        printf("\n");
                }
                fclose(fptr);
                return 0;
        }

输出：

Naruto  Wind 85 48 35 63
Neji  Fire 57 53 81 45
Gaara  Earth 73 47 96 50
Sasuke  Fire 68 82 72 41
Kankurou  Water 59 42 97 60
