Question

在我的C代码中，employee.h看起来像这样：

typedef struct Employee {
    int Id;
    char Name[100];
    int Age;
    long Salary;
}Employee;

我要做的是创建一个显示身份证，员工，年龄和薪水的报告。但我似乎无法弄清楚如何将每个东西与文件分开。此外，我的输出一直在跳过文件中的行，如果我可以像我计划的那样将它们分开，我肯定会修复它。文件和输出将位于底部以显示其外观。这只是我的任务的一部分，但搞清楚这将有助于我完成剩下的工作。希望有来自这里的人可以帮助我。

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

void printemployeeByPointer(Employee * e) {
    printf("Id:%d Name:%s Age:%d Salary:%ld\n",e->Id,e->Name,e->Age,e->Salary);
}

void stripNewLine(char * s) {
    int len = strlen(s);
    if(len < 1)
        return;
    if(*(s + len - 1) == '\n')
        *(s + len - 1) = '\0';
}

int main(){
    int i;
    int counter=0;
    char buffer[2000];      
    Employee * Emp;

    //open .txt
    FILE * fp = fopen("file.txt", "r");
    if(fp == NULL) {
        printf("cannot open file!\n");
        return EXIT_FAILURE;
    }

    //read in (2 lines in our file per fruit)
    while(!feof(fp)) {
        //make a heap
        Emp = (Employee *) malloc(sizeof(Employee));
        //check null
        if(Emp == NULL) {
            //skip this iteration
        }
        //read in Id
        if(fgets(buffer, 2000, fp) == NULL) {
            //if fgets returns NULL then we have a problem with file
            //so skip this iteration
        }

        Emp->Id = atoi(buffer);

        //read in name
        if(fgets(buffer, 2000, fp) == NULL) {
            //if fgets returns NULL then we have a problem with file
            //so skip this iteration
        }
        stripNewLine(buffer);
        strcpy(Emp->Name, buffer);

        //read in Age
        if(fgets(buffer, 2000, fp) == NULL) {
            //if fgets returns NULL then we have a problem with file
            //so skip this iteration
        }

        Emp->Age = atoi(buffer);

        //read in Salary
        if(fgets(buffer, 2000, fp) == NULL) {
            //if fgets returns NULL then we have a problem with file
            //so skip this iteration
        }

        Emp->Salary = atoi(buffer);
        printemployeeByPointer(Emp);
        free(Emp);
        counter++;
    }

    //close file
    fclose(fp);

    return EXIT_SUCCESS;
}

Answer 1

fgets（）读取你要求的字符数（直到行尾）;你正在对待它，好像它每次调用只读取一个项目。你尝试将整行解析为一个数字，每个ID b / c得到0，这个数字总是以一个单词开头;然后你读下一行，然后设置名称;然后阅读接下来的两行，尝试将每个行解析为一个数字（见上文）。所以你为每个员工读了3行，这就是你每次跳过3行的原因。（为什么你要malloc员工，只在每次迭代结束时释放它？）

如何将文件中的单独内容放入不同的数组中，以便打印出我需要它的方式？
