fopen读取不了文件
程序代码：#include<iostream>
#include<stdio.h>
#include<string.h>
//void main_1(int *n_file_, FILE *open, FILE *write_8, FILE *write_9, FILE *write_10, FILE *write_11, FILE *write_12, FILE *write_13, FILE *write_14, FILE *write_15, FILE *write_16);
void main_1(int * n_file_, FILE * open, FILE ** f_write_);
void file_write(unsigned char *, FILE *);
int length(unsigned char *a);//可以设定多个条件
int main()
{
FILE *f_open = NULL;//打开目标文件，可以改成把文件拖进来的相对路径
int n_file_[9] = { 0 };
if (fopen("test.txt","r+")==NULL)
puts("打开文件成功\n\n");
else
{
puts("打开文件失败\n\n");
return 0;
}
FILE *f_write_[9] = { NULL };//生成的文件
f_write_[0] = fopen("length_1_8", "wb+");
f_write_[1] = fopen("length_9", "wb+");
f_write_[2] = fopen("length_10", "wb+");
f_write_[3] = fopen("length_11", "wb+");
f_write_[4] = fopen("length_12", "wb+");
f_write_[5] = fopen("length_13", "wb+");
f_write_[6] = fopen("length_14", "wb+");
f_write_[7] = fopen("length_15", "wb+");
f_write_[8] = fopen("length_over15", "wb+");
//main_1读取数据，分别写入相对于的文件
main_1(n_file_, f_open, f_write_);
// cul(f_write_[0],n_file_[0]);//目标文件；文件存储长度
fclose(f_open);
for (int i = 0; i < 9; i++)
fclose(f_write_[i]);
return 0;
}
//void main_1(int *n_file_, FILE *open, FILE *write_8, FILE *write_9, FILE *write_10, FILE *write_11, FILE *write_12, FILE *write_13, FILE *write_14, FILE *write_15, FILE *write_16)
void main_1(int * n_file_, FILE * open, FILE ** file)
{
// FILE *file[9] = { write_8, write_9, write_10, write_11, write_12, write_13, write_14, write_15, write_16 };
unsigned char temp[20];
int i;
while (!feof(open))//判断是否到文件尾部
{
fscanf(open, "%s ", temp);//从文件读取一个字符串
i = length(temp);//根据字符串长度确定输入哪一个文件,若返回值为0，则跳过这个字符串
if (i == 0)
continue;
else if (i < 9)//写入对应的文件
{
file_write(temp, file[0]);
n_file_[0]++;
}
else if (i>15)
{
file_write(temp, file[8]);
n_file_[8]++;
}
else
{
file_write(temp, file[i - 8]);
n_file_[i - 8]++;
}
}
}
int length(unsigned char *a)//可以设定多个条件
{
static int n = 0;
if (n++ % 5 != 2)
return 0;
return strlen((char *)a);
}
void file_write(unsigned char * a, FILE * file)
{
fprintf(file, "%s", a);
fprintf(file, " ");
}昨天程序调试的时候还能正常运行，今天早上把一个200M左右的文件进行操作，没成功；之后就出现了无法读取文件的情况：代码调试以后，f_open总是无法读取到内存然后就结束了。
