C - 按输出顺序打印的问题

Question

我在按我希望的顺序打印到控制台时遇到问题，我不知道为什么。代码的逻辑似乎很好，但它无法按照所需的顺序打印内容。输入取自逐行读取的文件，直到文件末尾。

输出：

Author: Brian Kernighan
Class: Student
Returns: the matric
Method: getMatric
Parameter: matric the matric number
Method: setMatric
Returns: the name
Method: getName
Parameter: name the name
Method: setName
Returns: the address
Method: getAddress
Parameter: address the address
Method: setAddress
Returns: a string representation of the Student
Method: toString
The total number of lines is 65
The total number of  non-blank lines is 56
The total number of comments is 8

这是所需的输出：

Class: Student
Author: Brian Kernighan 
Method: getMatric
Returns: the matric 
Method: setMatric
Parameter: matric the matric number 
Method: getName
Returns: the name 
Method: setName
Parameter: name the name 
Method: getAddress
Returns: the address 
Method: setAddress
Parameter: address the address 
Method: toString
Returns: a string representation of the Student 
Total number of lines: 65
Number of non-blank lines: 56
Number of Javadoc comments: 8

有谁知道为什么会这样？在这里我也附上我当前的代码：

  printf("The total number of comments is %d\n", total_comments);

  fclose(input);
  fclose(output);
  return 0;
}

输入文件是这个：

/**

 */
public class Student {

    private int matric;
    private String name;
    private String address;

    /**
     * Query for the matric number of the student.
     * @return the matric
     */
    public int getMatric (  ) {
        return this.matric;
    }

    /**

     * @param matric the matric number
     */
    public void setMatric ( int matric ) {
        this.matric = matric;
    }

    /**

    public String getName ( ) {
        return this.name;
    }

代替 while 循环局部的整数标志，变量的第一个字符可用于控制打印。
将参数的打印和 return 放在方法的打印中，因此方法先出现。

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