How to properly use fscanf in this file - c

Question

I have this file with the following contents:
Bob Human, 1
John Cat, 3
Mary Dog, 2
How can I properly use fscanf to have each string and integer in a struct.
typedef struct {
char name[20];
char surname[20];
int code;
} entry;
Then I create an array of _entry_
entry a[3];
How will _a_ get each value properly using fscanf?
EDIT :
I have tried this:
while(TRUE) {
nscan=fscanf(infile, "%s %s d%c", temp.name, temp.surname, &temp.code, &termch);
if(nscan==EOF) break;
if(nscan!=4 || termch!='\n') {
printf("Error\n");
}
RecBSTInsert(&a, temp);
}
But it seems to pass the last line twice.

Answer 1

You're close, but you're not handling the comma properly.
As usual, it's much easier to read whole lines, then parse them. So let's do that.
Try:
char line[1024];
if(fgets(line, sizeof line, infile) != NULL)
{
nscan = sscanf(line, "%s %[^,], %d", temp.name, temp.surname, &temp.code);
}
The return value will be 3 if all the fields converted, else you have an error.

Answer 2

#include <stdio.h>
typedef struct{
char name[20];
char surname[20];
int code;
} entry;
int main(){
entry temp, a[3];
FILE *infile = fopen("data.txt", "r");
int i=0, n;
while(fscanf(infile, "%19s %19[^,], %d", temp.name, temp.surname, &temp.code)==3){
a[i++] = temp;
if(i==3)break;
}
fclose(infile);
n = i;
for(i=0;i<n;++i){
printf("%s %s, %d\n", a[i].name, a[i].surname, a[i].code);
}
return 0;
}
