c - C语言中如何将输出自动存储​​到文本文件中？

Question

嘿。 我正在制作一份应该能够打印出来以添加签名的文档。我在 C 程序的输出中有该文档，但是保存时我只得到代码，而不是最终输出。 这是我的代码:

#include <stdio.h>

int main(void)

{

   FILE*pfile=NULL;

   pfile=fopen("MY_FILE","r");

   printf("Digital Forensics Investigation Documentation Evidence Form\n\n");
   printf("Section 1: Evidence Item Record\n");

   printf("---------------------------------\n");

char array1[20][100]={"\nLab reference Number:","\nCase reference Number:","\nItem reference Number:","\nDevice Description:","\nAdditional Information:","\nSection 2: Investigator Details\n\nDevice accepted by:","\nDate and time received:","-------------------------------------------------------------------------","\n\nSignaure:\n","\n\n------------------"};

char array2[20][500]={"TDI-DF","DFI-C001-2014-10-108","EI-201","Western Digital external hard drive,1TB","\nBlack case,with a few scratches on the side and chipped corner.\nNo obvious serial number or other distinguising features.\nPower cable and USB cable still attached.\nReceived from CTO organisation.\nIt was attached to a laptop running windows 8.\nThis laptop was powered of at the time this harddrive was removed.\n\n-------------------------------------------------------------------------","Sara Hansen","30th December 2014 at 15:00"};
int i;

for (i=0;i<20;i++)

{

 printf("%s  %s \n", array1[i], array2[i]);

}

fscanf(pfile,"d% d% d%");

fclose(pfile);

    return 0;
}

我希望我的输出保存在文本文档asell中，而不仅仅是代码中。

任何人都可以帮我找出我的代码中缺少的内容，以便将其以正确的格式保存在文本文件中吗？

谢谢!

您需要使用 w 模式和 fopen 才能编写:

pfile = fopen("MY_FILE", "w");

然后使用fprintf代替printf，例如:

fprintf(pfile, "Digital Forensics Investigation Documentation Evidence Form\n\n");

不确定您的 fscanf 行正在尝试完成什么任务。
