将文本添加到行尾

Question

我正在处理文件。我想把每一行都分开，并在空格后分开。 例如，如果一号线有：今天是星期一我希望能有今天，是，周一separatly为了对他们的工作

这是到目前为止我的代码：

FILE *file = fopen ("file1", "r"); 

      if ((file != NULL)) 
      { 
       char line [ 128 ]; 
       while((fgets (line, sizeof line, file) != NULL)) 
       { 
       //tokenize the line based on space 

       ?? 

       } 
how to add text at the end of the line? i mean i have **today is monday** and i want to add for example **Yupppy** at the end of today is monday line. 

      fclose (file); 

      }

来标记一个字符串即可使用strtok() 检查我的链接后的例子，只是改变分隔空间：

（从链接的示例代码）

#include <stdio.h> 
#include <string.h> 




int main() 
{ 
  char str[] ="- This, a sample string."; 
  char * pch; 
  printf ("Splitting string \"%s\" into tokens:\n",str); 
  pch = strtok (str," "); 
  while (pch != NULL) 
  { 
    printf ("%s\n",pch); 
    pch = strtok (NULL, " "); 
  } 
  return 0; 
}
