错误C4996:Visual Studio:在C中使用fopen时为什么会出现错误? [英] error C4996: visual studio: why do I get an error when I use fopen in c?

问题描述

我刚刚开始使用文件，所以我制作了一个仅打开文件的程序，但出现错误:

I just started to work with files so I made this program that just opens a file but i get the error:

error C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

下面是代码:

#include <stdio.h>

int main()
{
    FILE* f = fopen("myFile.txt", "w");
    if (f == NULL)
    {
        printf("error\n");
        return;
    }
    fclose(f);
}

推荐答案

您需要在包含之前放置 #define _CRT_SECURE_NO_DEPRECATE 的定义.喜欢，

You need to place a definition of #define _CRT_SECURE_NO_DEPRECATE before your include. Like,

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
