wrong result,while debugger shows it right

i had made a thread yesterday where i had problems with passing values to a struct. Now, i fixed that but, i can't open the files.(i have started programming on linux)

Here is the code

Code:

---

void read_inputs(bankT array[],int size,FILE* input_file){
    int i,nscan;
    char termch;
    for(i=0; i<size; i++){
        nscan = fscanf(input_file,"%30[^,], %d, %lf, %d%c",array[i].epwnymo,&array[i].ypolipo,&array[i].epitokio,&array[i].hmeromhnia,&termch);
        if (nscan == EOF) break;
        if (nscan != 5 || termch != '\n'){
            Error("Improper file format");
        }
    }

---

I get the "Improper file format" even though the results with debugging are:

Code:

---

nscan = 5
termch= 10'\n'

---

Sorry for many posts, but since i am new to linux, i have some troubles

Well, that's tough. As a temporary debugging measure, try printing the value of nscan and termch to see if they match with what your debugger tells you.

Instead of this termch idea, maybe it would be easier if you use fgets to read the line, then sscanf to parse it? You would also be better able to differentiate between an error in reading and an error in parsing.

if i remove this :

Code:

---

if (nscan != 5 || termch != '\n'){            Error("Improper file format");
        }

---

It works fine, and I can continue to next steps of my exercise, but I need a warning in case someone makes a mistake.

With this:

Code:

---

    printf("%d %c",nscan,termch);

---

The result is:

Code:

---

//5
//5

---

Well, what about this instead?

Code:

---

void read_inputs(bankT array[], int size, FILE* input_file) {
    char line[BUFSIZ];
    int i;
    for (i = 0; i < size && fgets(line, sizeof(line), input_file); i++) {
        if (sscanf(line, "%30[^,], %d, %lf, %d", array[i].epwnymo, &array[i].ypolipo, &array[i].epitokio, &array[i].hmeromhnia) != 4) {
            Error("Improper file format");
        }
    }

Please post runnable programs instead of just snippets. What you describe in your first post is, on the surface, impossible, which suggests you've left out something important. You should also show your input file. Try doing a cat -E of it (which displays a $ at the end of each line) to see if there's extraneous space at the end of any lines.

laserlight's suggestion does not quite do the job you seem to be requesting as it doesn't ensure that there are no extra characters on the line.

Maybe something like this:

Code:

---

void read_inputs(bankT array[], int size, FILE* input_file){
  int i, nscan, termch;
  for (i = 0; i < size; i++){
    nscan = fscanf(input_file, "%30[^,], %d, %lf, %d",
                  array[i].epwnymo, &array[i].ypolipo,
                  &array[i].epitokio, &array[i].hmeromhnia);
    if (nscan == EOF) break;
    while (isspace(termch = fgetc(input_file)) && termch != '\n')
      ;
    if (nscan != 4 || termch != '\n')
      Error("Improper file format\n");
  }
}
