C - “文件”错误的冲突类型

Question

When I try to compile my C program, I get the following error:

file.c:16:1: error: conflicting types for 'file'

concerning this code:

char *filename = "dictionary.txt";
FILE *file;
file = fopen(filename, "a+");

I have used the article as a reference: C File I/O and Binary File I/O

Any help would be much appreciated, and thanks in advance.

Answer 1

With this code I get the same error: conflicting types for 'file' . Note the definition of file twice in the same scope.

#include <stdio.h>

int main(void) {
    int file = 0;

    char *filename = "dictionary.txt";
    FILE *file;
    file = fopen(filename, "a+");

    return 0;
}

Making sure there is not another variable named file in the same scope should solve the problem.

For example I don't get a compiler error with this version:

#include <stdio.h>

int main(void) {
    int file = 0;

    {
        char *filename = "dictionary.txt";
        FILE *file;
        file = fopen(filename, "a+");
    }
    return 0;
}

The article you link to actually uses fp for the FILE * variable name, but if your own code doesn't elsewhere define a file , then somewhere a header file you are directly or indirectly using is defining something called file . Without knowing your platform, it's hard to say which header file would be defining a file .
