c - 将 .txt 文件存储到结构中

Question

我正在尝试将 .txt 文件存储到结构中，但没有成功。我不需要存储第一行，但我确实需要其余的。多谢你们 !! =)

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

int main(int argc, const char * argv[]) {
    // insert code here...
    printf("Hello, World!\n");

    struct candidates
    {
        char name[25];
        char gender[5];
        int height;
        int weight;
    };

    struct candidates values[25];

    FILE *fp;
    if ((fp=fopen("candidatesdata.txt","r"))==NULL){printf("Unable to open file\n");}


    int x = 0;
    int iterations = 0;
    while((fscanf(fp,"%s,%s,%d,%d",&values[x].name, &values[x].gender, &values[x].height, &values[x].weight))!=EOF)
        {
            x++;
            iterations +=1;
        }
    fclose(fp);

    //values[15].weight = 300;

    printf("\n%d\t%d",iterations,values[1].height);


    return 0;
}

文本文件如下所示:

Name,Gender,Height,Weight
Tanner,M,71.8,180.25
John,M,70.75,185.3
Parker,F,65.25,120.3
Meeks,M,57.25,210.2

Answer 1

struct candidates
    {
        char name[25];
        char gender[5]; // can be char gender too !!
        int height; // should be changed to float height
        int weight; // should be changed to float height
    };

如果您实际上有:

Name,Gender,Height,Weight

在你的文件中，你可以在进入 while 循环之前执行他的操作:

char somebigstring[100];
.
.
.
if(fscanf(fp,"%s",somebigstring) == EOF) //wasting the first line
   exit(-1); // exiting here if there is no first line
