Simple question about files.

I am using the following code to open a .dat file and display it. My dat file has something like this:
George Michael 17
Michelle Anderson 35
Britney Lobele 19

This is the code I am using.....

Code:

---

#include <stdio.h>

int main()
{
        FILE *file;
        char first_name[15];
        char last_name[15];
        int age;

        if((file = fopen("people.dat", "r")) == NULL)
                printf("File could not be opened.\n");
        else
        {
                printf("First Name\tLast Name\tAge\n");

                while(!feof(file))
                {
                        fscanf(file, "%s%s%i", &first_name, &last_name, &age);
                        printf("%10s%15s%10i\n", first_name, last_name, age);
                }
            fclose(file);
        }
        return 0;
}

---

The problem is that the last line in the file is being diplsyed twice, like this:
George Michael 17
Michelle Anderson 35
Britney Lobele 19
Britney Lobele 19

How can I fix this?
Thanks.

That's because you probably have a space or new line in the end of your file. There should be no character after the last correct character in your file.

Check fscanf return values ie:

Code:

---

#include <stdio.h>

int main()
{
        FILE *file;
        char first_name[15];
        char last_name[15];
        int age;
                    int retval;
        if((file = fopen("people.dat", "r")) == NULL)
                printf("File could not be opened.\n");
        else
        {
                printf("First Name\tLast Name\tAge\n");

                while(!feof(file))
                {
                        retval=fscanf(file, "%s%s%i", &first_name, &last_name, &age);
                        if(retval!=EOF)printf("%10s%15s%10i\n", first_name, last_name, age);
                }
            fclose(file);
        }
        return 0;
}
