Getting extra characters while reading records from a file using structure.

Question

I wrote a C program to read records from a file using structure but when i compiled it i got few extra characters apart from those which are written in my file "EMPLOYEE". So Please resolve my issue. Screenshot of the file content and debug console has been attached herewith.
Here is the C Program---

include<stdio.h>

include<conio.h>

include<stdlib.h>

int main()
{
FILE* fp;
errno_t err;
char another = 'Y';
struct emp
{
char name[31];
int age;
float bs;
};
struct emp e;
err = fopen_s(&fp, "EMPLOYEE.DAT", "r");
if (err != 0)
{
puts("Can Not Open file");
exit(1);
}
else
while ((fscanf_s(fp,"%s%d%f",e.name, sizeof(e.name), &e.age, &e.bs)) != EOF)
printf("%s%d%f\n", e.name, e.age, e.bs);
fclose(fp);
return 0;
}

Answer 1

Assuming that the first 2 characters are name, the next two characters are age and the remainder of the line is the bs float try this -

        while ((fscanf_s(fp, "%2s%2d%f", e.name,  (unsigned int) _countof(e.name), &e.age, &e.bs)) != EOF)
            printf("%s %d %f\n", e.name, e.age, e.bs);

Answer 2

Hello,
did you check the variables with the debugger?
IMO, fscanf is the wrong approach. %s will read the full string "lk2587000.0000" . To separate the values to "lk", 2587000 and 0.0 , you must implement your own string analysis routine.

In addition: it is always usefull to initialize the values of a variable/struct/etc.
