print an int array in a file in C - c

Question

I need to write a file(not binary) with students and each ones grades(int note[10] under this form). I do not get any errors but when I try to write the file just the last grade is printed, and I don't know how to print the entire list. For example (int nr_note means how many grades does the student have) if a students grades are 6, 8, 9 it just prints the 9.
Thank you in advance.
#include <stdio.h>
#include <stdlib.h>
struct student{
int nr_matricol;
char nume[10];
int nr_note;
int note[10];
};
void citire_date(struct student *studenti, int n, FILE *f){
int i, j;
for(i=0;i<n;i++){
printf("Studentul %d\n", i+1);
printf("Numarul matricol: "); scanf("%d", &(studenti+i)->nr_matricol);
printf("Numele studentului: "); fflush(stdin); gets((studenti+i)->nume);
printf("Numarul de note: "); scanf("%d", &(studenti+i)->nr_note);
for(j=0;j<((studenti+i)->nr_note);j++){
printf("Nota %d: ", j+1); scanf("%d", &(studenti+i)->note[i]);
}
fprintf(f, "Numar matricol: %d\nNume: %s\nNote: %d \n", ((studenti+i)->nr_matricol) ,((studenti+i)->nume), ((studenti+i)->note[i]));
}
}
int main()
{
struct student studenti[20];
FILE *f;
int n;
f = fopen("studenti.txt", "w");
if(f==NULL){
printf("Nu s-a putut deschide/crea fisierul pentru scriere.");
exit(1);
}
printf("Introduceti numarul de studenti: "); scanf("%d", &n);
citire_date(studenti, n, f);
fclose(f);
return 0;
}

Answer 1

Change citire_date() function like this :
void citire_date(struct student *studenti, int n, FILE *f){
int i, j;
for(i=0;i<n;i++){
printf("Studentul %d\n", i+1);
printf("Numarul matricol: "); scanf("%d", &(studenti+i)->nr_matricol);
printf("Numele studentului: "); fflush(stdin); gets((studenti+i)->nume);
printf("Numarul de note: "); scanf("%d", &(studenti+i)->nr_note);
for(j=0;j<((studenti+i)->nr_note);j++){
printf("Nota %d: ", j+1); scanf("%d", &(studenti+i)->note[j]);
}
fprintf(f, "Numar matricol: %d\nNume: %s\n", ((studenti+i)->nr_matricol) ,((studenti+i)->nume) );
// Printing the notes
for(j=0;j<((studenti+i)->nr_note);j++){
fprintf(f, "Note: %d = %d \n", j+1, ((studenti+i)->note[j]));
}
}
}
You need to use a loop to print all the notes.
