如何读取文件中的数据，并将其传递给结构体~>C [英] How to read through data in a file, and pass it to a struct ~> C

问题描述

好的.我的主目录中有一个名为Graduates.txt"的文件.
我有一个可移植的程序来查找主目录，我打开文件进行阅读.
文件中的数据如下所示:

Okay. I have a file called "Graduates.txt" in my home directory.
I have a portable program to find the home directory, and I opened the file for reading.
Data in the file looks something like this:

year,firstName,lastName

我需要从这个文件中获取这些数据，并将其分离到我的结构中:

I need to get this data from this file, and separate it into my struct:

typedef struct alumnus {

    int yearGraduated;
    char firstName[30];
    char lastName[30];

} Alumns;

我有一个想法，可能行得通，也可能行不通:
while 循环读取文件，使用 fgets() 获取数据.然后它将它复制到结构......但我不知道如何实现这些.

I have a thought that may or may not work:
A while loop reads through the file, using fgets() to get the data. It then copies it to the struct... but I don't know how to implement any of this.

抱歉，如果这听起来像个愚蠢的问题，那很可能是.

Sorry if this sounds like dumb question, it most likely is.

推荐答案

#include <stdio.h>

typedef struct alumnus {
    int yearGraduated;
    char firstName[30];
    char lastName[30];
}Alumns;

int main(void) {

    Alumns REC1;

    FILE *fptr;
    fptr = fopen("Test.txt", "r");

    fscanf(fptr, "%d,%s,%s", &REC1.yearGraduated, REC1.firstName, REC1.lastName);

    printf("%d, %s, %s", REC1.yearGraduated, REC1.firstName, REC1.lastName);
}

使用 dasblinkenlight 提示实现.

Implemented using dasblinkenlight hint.
