在同一个 .c 文件中写入和读取时，fscanf 不会读取文本文件中的所有值

Question

有一个问题，我需要在一个文本文件中写入 10001 个 int 值，然后在同一个程序中，这些值应该被读取并存储在一个 int 值中以找出总和。但是，当我在同一个程序（同一个 .c 文件？）中执行这两项操作时，它不会读取最后 200 个值，因此总数比预期的要少。如果您知道是什么原因造成的，请写信，因为我们将不胜感激 :) 提前谢谢您！

Ps：我是编码的初学者，尤其是 C 编程的初学者，如果我的代码有严重的错误，请原谅我......

#include <stdio.h>

 int main ()
 {
 //a)

 FILE * fp = fopen ("deneme.txt","w");

 int I;

 for(i=0;i<=10001;i++) {
            
        if(i%10==0){
            
            fprintf(fp,"\n");
            
        }
        
            fprintf(fp,"%5d  ",i);
        
}

´ /* when i write and read in different .c 
 files, it shows the correct answer which is:
 
 Total sum: 50015001
 from how many values: 10002

 but instead it gives me this:
 Total sum: 48083730
 from how many values: 9808
 
 */´

//b)

       FILE* file = fopen ("deneme.txt", "r");
       int j,counter =0;
       int sum = 0;  
  
      while ((fscanf (file, "%d", &j)) != EOF)
      {  
         counter++;
          sum+=j;
           
      }
      
      fprintf(stdout,"Total sum: %d\n",sum);
       printf("from how many values: %d",counter);
    
    
      fclose (file);
  
   return 0;   
 }

这行得通

#include <stdio.h>

int main ()
{
    //a)

    FILE * fp = fopen ("deneme.txt","w");
    int i;//YOU HAD A TYPO HERE
    for(i=0;i<=10001;i++) { 
        if(i%10==0){
            fprintf(fp,"\n");
        }
        fprintf(fp,"%5d  ",i);
    }

    fclose(fp); //ADD THIS

    //b)

    FILE* file = fopen ("deneme.txt", "r");
    int j,counter =0;
    int sum = 0;  
    while ((fscanf (file, "%d", &j)) != EOF)
    {  
        counter++;
        sum+=j;
        
    }
    fprintf(stdout,"Total sum: %d\n",sum);
    printf("from how many values: %d",counter);
    fclose (file);
    return 0;
        
}
