Code::Blocks：带有指针 FILE 参数的函数（和函数原型）出错

Question

所以我正在做一些基本的 C 然后我被阻止了。

我想计算文件中的行数。函数和原型函数在.c（对于函数）和.h（对于原型函数）中，问题是我得到错误

注意：我使用的编译器是 GNU GCC C++ 14 ISO

来自 Function.c :

#include "Functions.h"

int FileLineCount(FILE *file)
{
    rewind(file);

    int iCount = 0;
    char string[MAX_CHARACTER_SIZE] = "";

    while((fgets(string, MAX_CHARACTER_SIZE, file) != NULL))
    {
        iCount++;
    }

    return iCount;
}

来自 Function.h :

#ifndef __FUNCTIONS_INCLUDED__
#define __FONCTIONS_INCLUDED__

int FileLineCount(FILE *file);

#endif

来自main.c :

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include "Functions.h"

#define MAX_CHARACTER_SIZE 256

int main()
{
    FILE *WordsFile = NULL;
    const char strWorldFileName[] = "RandomWords.txt";
    WordsFile = fopen(strWorldFileName, "r");

    if(WordsFile == NULL)
    {
        printf("Error ! Impossible to open the file %s\n", strWorldFileName);
        printf("Verify if this .txt file is in the folder where the file main.c is in it\n");
        return EXIT_FAILURE;
    }

    printf("Line count : %i\n\n", FileLineCount(WordsFile));
}

这是编译器的错误：

error: unknown type name 'FILE'
error: unknown type name 'FILE'

Answer 1

#include <stdio.h>

在您的 Functions.h 文件中

并将其修复为相同的 'functions' 和 'fonctions'

#ifndef __FUNCTIONS_INCLUDED__
#define __FONCTIONS_INCLUDED__
