关于VS2022 fopen_s函数错误
#include <stdio.h>
#include <stdlib.h>
//#define _CRT_SECURE_NO_WARNINGS
int main(void)
{
FILE* fp;
FILE *p;
int ch;
if ((fp = fopen_s("p", "text.txt","r")) == NULL)
{
printf("打开文件失败!\n");
exit(EXIT_FAILURE);
}
while ((ch = getc(fp)) != EOF)
{
putchar(ch);
}
fclose(fp);
return 0;
}
在同级文件夹放了个文件,但打开后程序自动关闭
int fp
if ((fp = fopen_s(&p, "text.txt","r")) != 0)
fopen_s的参数和fopen是不一样的,仔细看看吧

fopen_s第一个参数错了吧?
