reading string and integers from file - c

Question

I have been trying to read some strings and integers from a file,but it seems that I don't do it correctly...This programm is supposed to read data from a file...It must create a list with the names of writters.For every writter,it should use a struct like the one I used here...Foe every writter's text,I must also create a struct,like the one I did here..Then,I have to sort the list,create another list with the most popular writers and then print the output...My program is:
#include<stdio.h>
#include<math.h>
#include<ctype.h>
#include<stdlib.h>
#include<string.h>
struct AuthorRecord {
char textTitle[30];
long Download;
struct AuthorRecord *next;
};
typedef struct AuthorRecord *AuthorRecordType;
typedef struct {
char firstName[30];
char lastName[30];
int idNumber,s1;
long s2;
float p;
AuthorRecordType text;
} AuthorType;
struct MemberNodeStruct {
AuthorType *anAuthor;
struct MemberNodeStruct *next;
};
typedef struct MemberNodeStruct *MemberNodeType;
int main()
{
int m,n,i,j,d,z,e,y;
long k;
char s[30];
AuthorType *a;
struct MemberNodeStruct *l,*l2,*temp,*min,*b1,*b2,*r,*r2,*r3;
struct AuthorRecord *t,*t2,*h,*h2,*min2,*temp2;
FILE *f;
f=fopen("project.txt","rt");
if(f==NULL)
exit(-1);
l2=NULL;
t2=NULL;
t=NULL;
fscanf(f,"%d",&n);
getchar();
for(i=1;i<=n;i++)
{
y=0;
a=(AuthorType*)malloc(sizeof( AuthorType));
fgets(s,30,f);
strcpy(a->firstName,s);
fgets(s,30,f);
strcpy(a->lastName,s);
fscanf(f,"%d",&d);
getchar();
a->idNumber=d;
fscanf(f,"%d",&m);
getchar();
t2=NULL;
a->s1=m;
a->s2=0;
for(j=1;j<=m;j++)
{
t=(struct AuthorRecord*)malloc(sizeof(struct AuthorRecord));
fgets(s,30,f);
e=0;
h=t2;
while(e==0 && h!=NULL)
{
if(strcmp(h->textTitle,s)==0)
{
e=1;
h2=h;
}
else
h=h->next;
}
if(e==0)
{
strcpy( t->textTitle,s);
fscanf(f,"%ld",&k);
getchar();
t->Download=k;
a->s2=a->s2+t->Download;
t->next=t2;
t2=t;
}
else
{
y=y+1;
fscanf(f,"%ld",&k);
getchar();
h2->Download=h2->Download+k;
a->s2=a->s2+k;
}
}
a->s1=a->s1-y;
a->p=round(a->s2/a->s1);
a->text=t2;
l=(struct MemberNodeStruct*)malloc(sizeof(struct MemberNodeStruct));
l->anAuthor=a;
l->next=l2;
l2=l;
}
........ (150 more lines of code)
.....
system("pause")
return(0);
I have tried this program with scanf and gets instead of a file and fscanf and fgets and it worked correctly...That's the reason I don't write the rest of my code.

Whenever I run this program,it ends up in a failure...For some reason,it demands input from me...I tried to remove the getchar() but still, it didn't work! What should I do?

Answer 1

It reads input from stdin, because you told it to do that :
fscanf(f,"%d",&n);
getchar();
Try making sure, you don't have anything reading input from default (file descriptor 0).
If you need to read 1 char from f, then use fgetc instead of getchar.
