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.

我有一个c程序：

(n-k)/2

然而它只打印：

BEAR. Large beast.

我想要打印：

BEAR. Large beast.

Answer 1

在DOS / Windows计算机上创建的文本文件与在Unix / Linux上创建的文件具有不同的行结尾。 DOS使用回车符和换行符（“\ r \ n”）作为行结尾，Unix只使用换行符（“\ n”）。您需要注意在Windows机器和Unix机器之间传输文件，以确保正确转换行结束。

/*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);
}
