Please help with this C code on files.

[Alwyn]

struct lib
{
char *name,*author,*publish;
int price;
int no;
}u[50];

FILE *fp;

void fin()  //Inputs data to a file
{  int i;
fp=fopen("abc.txt","w");

for(i=1;i<=n;i++)
{

fprintf(fp,"%s",&u[i].name);

putc('\t',fp);
fprintf(fp,"%s",&u[i].author);

putc('\t',fp);
fprintf(fp,"%s",&u[i].publish);

putc('\t',fp);
fprintf(fp,"%d",u[i].price);
putc('\t',fp);
fprintf(fp,"%d",u[i].no);
putc('\n',fp);

}

fclose(fp);

}



void fout() // Reads data from the file 
{
int i,x,j=0;
char c,d[50];
d[0]='\0';
fp=fopen("abc.txt","r");
for(i=1;i<=n;i++)
{
fscanf(fp,"%s",u[i].name);
while((c=getc(fp))!='\t') ;

fscanf(fp,"%s",u[i].author);
while((c=getc(fp))!='\t') ;

fscanf(fp,"%s",u[i].publish);
while((c=getc(fp))!='\t') ;

fscanf(fp,"%d",&u[i].price);
while((c=getc(fp))!='\t') ;

fscanf(fp,"%d",&u[i].no);
while((c=getc(fp))!='\n') ;

}
fclose(fp);

}

The strings read from the file are not stored in the structure. If I try to display the strings they appear as <null> . The numbers are input without any problem.
Please help as soon as possible.

the following are pointers

char *name,*author,*publish;

but what do they point too?
should they be arrays?

char name[20],author[20],publish[20];
