Question

我正在尝试让我的代码用文件中的数据填充结构中的数组。

截至目前，它还没有编译，只是给出了标题中的错误。

我希望能够解决这个问题，以便继续研究代码，但最近4小时对我没有任何作用......

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

#define MAX 100

FILE *fp;
FILE *fpIn;
FILE *fpOut;

typedef struct {
    char first[7];
    char initial[1];
    char last[9];
    char street[16];
    char city[11];
    char state[2];
    char zip[5];
    int age;
    char sex[1];
    int tenure;
    double salary;
    } workers;

void readFile();
void strsub (char buf[], char sub[], int start, int end);

int main()
{

        if (!(fpIn = fopen("payfile.txt", "r")))
    {
        printf("payfile.txt could not be opened for input.");
        exit(1);
    }
    if (!(fpOut = fopen("csis.txt", "w")))
    {
        printf("csis.txt could not be opened for output.");
        exit(1);
    }

    return 0;
}

void readFile()
{
    char buf[MAX];
    while(!feof(fpIn))
    {
        fgets(buf, MAX, fpIn);
        strsub(buf, workers[i].first, 0, 6);
        strsub(buf, workers[i].initial, 8, 8);
        strsub(buf, workers[i].last, 10, 18);
        strsub(buf, workers[i].street, 20, 35);
        strsub(buf, workers[i].city, 37, 47);
        strsub(buf, workers[i].state, 49, 50);
        strsub(buf, workers[i].zip, 52, 56);
        strsub(buf, workers[i].age, 58, 59);
        strsub(buf, workers[i].sex, 61, 61);
        strsub(buf, workers[i].tenure, 63, 63);
        strsub(buf, workers[i].salary, 65, 70);
    }
}

void strsub (char buf[], char sub[], int start, int end)
{
    int i, j;

    for (j=0, i=start; i <= end; i++, j++)
    {
        sub[j] = buf[i];
    }
    sub[j] = '\0';
}

我修复了你的程序编译，但它仍然有问题。我不得不评论一个类型不匹配，但至少这个编译，以便你有一些工作。

#include <stdio.h>

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

#define MAX 100

FILE *fp;
FILE *fpIn;
FILE *fpOut;

typedef struct {
    char first[7];
    char initial[1];
    char last[9];
    char street[16];
    char city[11];
    char state[2];
    char zip[5];
    int age;
    char sex[1];
    int tenure;
    double salary;
} workers;

void readFile();
void strsub (char buf[], char sub[], int start, int end);

int main()
{

    if (!(fpIn = fopen("payfile.txt", "r")))
    {
        printf("payfile.txt could not be opened for input.");
        exit(1);
    }
    if (!(fpOut = fopen("csis.txt", "w")))
    {
        printf("csis.txt could not be opened for output.");
        exit(1);
    }

    return 0;
}
workers array[8];
void readFile()
{
    int i =0;
    char buf[MAX];
    while(!feof(fpIn))
    {
        fgets(buf, MAX, fpIn);
        strsub(buf, array[i].first, 0, 6);
        strsub(buf, array[i].initial, 8, 8);
        strsub(buf, array[i].last, 10, 18);
        strsub(buf, array[i].street, 20, 35);
        strsub(buf, array[i].city, 37, 47);
        strsub(buf, array[i].state, 49, 50);
        strsub(buf, array[i].zip, 52, 56);
        strsub(buf, array[i].age, 58, 59);
        strsub(buf, array[i].sex, 61, 61);
        strsub(buf, array[i].tenure, 63, 63);
        //strsub(buf, array[i].salary, 65, 70);
    }
}

void strsub (char buf[], char sub[], int start, int end)
{
    int i, j;

    for (j=0, i=start; i <= end; i++, j++)
    {
        sub[j] = buf[i];
    }
    sub[j] = '\0';
}

参数太少错误
