#include <stdio.h>

int main()
{
    char filename[15];
    printf("Enter the filename: ");
    scanf("%s", filename);
   FILE* file = fopen (filename, "r");
    int i = 0;

    fscanf (file, "%d", &i);    
    while (!feof (file))
    {  
        printf ("%d", i);
        fscanf (file, "%d", &i);      
    }
    fclose (file);   
   return 0;
