C - 从文件中读取

Question

我有一个包含以下内容的文本文件：

ANT. Small insect,  
sometimes has wings on its back.

BEAR. Large beast.

我有交流程序：

int main(void)
{
   FILE *fp;
   int c;

   fp = fopen("myfile.txt","r");
   if(fp == NULL) 
   {
      perror("Error in opening file");
      return(-1);
   } do {
      c = fgetc(fp);
      if(feof(fp))
         break ;
    if (c != '\n')
        printf("%c", c);
   }while(1);

   fclose(fp);
}

但是它只打印：

BEAR. Large beast.

我希望它打印：

ANT. Small insect, sometimes has wings on its back.  
BEAR. Large beast.

Answer 1

在 DOS/Windows 机器上创建的文本文件与在 Unix/Linux 上创建的文件具有不同的行尾。 DOS 使用回车和换行（“\\r\\n”）作为行尾，而 Unix 只使用换行（“\\n”）。 在 Windows 机器和 Unix 机器之间传输文件时需要小心，以确保行尾正确翻译。

/*Everything looks find in your code. in my machine it is working fine . I have only added a if condition to print the contents same as the file thats it .. */

#include<stdio.h>

int main(void)
{
   FILE *fp;
   int c;

   fp = fopen("rabi.txt","r");
   if(fp == NULL)
   {
      perror("Error in opening file");
      return(-1);
   } do {
      c = fgetc(fp);
      if(feof(fp))
         break ;

        printf("%c", c);

        printf ("\n");
   }while(1);
printf ("\n");
   fclose(fp);
}
