Thread: Problem with fgets()

Hi everybody!!
I have this code:

Code:

#include <stdio.h>#include <string.h>
#include <stdlib.h>


struct lesson {
	char name[50];
	int grade;
};


struct student {
	char name[30];
	char surname[30];
	int AM;
	int year;
	int lessons_num;
	struct lesson *lessons;
};


 void print_data_base(struct student Students[],int n);


int main () {
 FILE *f;
 int n,m,i,j;
 char buff[100]="";
 struct student *Students;




    f=fopen("in.txt","r");
    if (f==NULL) {printf("error reading file!!");exit(1);}
    fscanf(f,"%d",&n);
    Students = (struct student*)malloc(n*sizeof(struct student));


    for (i=0;i<n;i++) {
        fscanf(f,"%s",Students[i].name);
        fscanf(f,"%s",Students[i].surname);
        fscanf(f,"%d",&Students[i].AM);
        fscanf(f,"%d",&Students[i].year);


        printf("%d ",Students[i].AM);
        printf("%s ",Students[i].name);
        printf("%s ",Students[i].surname);
        printf("%d ",Students[i].year);


        fscanf(f,"%d",&Students[i].lessons_num);//Πλήθος μαθημάτων
        printf("lessons_num=%d\n",Students[i].lessons_num);
        Students[i].lessons = (struct lesson*)malloc(Students[i].lessons_num * sizeof(struct lesson));


        int lessons_count;
        for(lessons_count=0; lessons_count<Students[i].lessons_num; lessons_count++){
            //fscanf(f, "%[^\n]s",Students[i].lessons[lessons_count].name);
            fgets(buff,100,f);
            printf("buff=%s\n",buff);
            strcpy(Students[i].lessons[lessons_count].name, buff);
            //fscanf(f, "%s" , Students[i].lessons[lessons_count].name);
            fscanf(f,"%d",&Students[i].lessons[lessons_count].grade);
            printf("%d. lesson: %s ",lessons_count,Students[i].lessons[lessons_count].name);
            printf("grade: %d\n",Students[i].lessons[lessons_count].grade);
        }
        getchar();
    }
    fclose(f);
    printf("print data base function...\n");getchar();
    //print_data_base(Students, n);


return 0;
}
void print_data_base(struct student Students[],int n){
    int i,j;


    for (i=0;i<n;i++) {
        printf("%d ",Students[i].AM);
        printf("%s ",Students[i].name);
        printf("%s ",Students[i].surname);
        printf("%d ",Students[i].year);
        printf("\n");
        for(j=0; j<Students[i].lessons_num; j++){
            printf("%s ",Students[i].lessons[j].name);
            printf("%d\n",Students[i].lessons[j].grade);
        }
    }
    printf("\n");
}//end print_data_base

and the attached text file as input file.
But something is going wrong with fgets()...
I cannont solve this problem..
please help!!
