Segmentation fault: 11 c structures - c

Question

I have an array of structure records and a function insert to insert or update the records.
The insert function take list(an array of records),name (book name),author, year,copies and size n of the list
It updates the record if it find's one otherwise inserts a new one. here n=7
void insert(struct books *list,char name[],char author[],int year,int copies,int n)
{
int i,found=0,empty;
for(i=0;(i<n) && (found==0);i++)
{
// update works fine
if( strcmp(name,list[i].name)==0 && strcmp(author,list[i].author)==0 )
{
list[i].copies=copies;
list[i].year=year;
printf("\n\n####################################################\n");
printf("####\tRecord was successfully updated!\t####\n");
printf("####################################################\n");
found=1;
}
//get an empty record
if(strcmp(list[i].author,"i")==0){empty=i;}
}
//insert gives segmentation error
if(found==0)
{
strcpy(list[empty].name,name);
strcpy(list[empty].author,author);
list[empty].year=year;
list[empty].copies=copies;
printf("\n\n####################################################\n");
printf("####\tRecord was successfully inserted!\t####\n");
printf("####################################################\n");
}
}
My list array is:

Why is it giving Segmentation error: 11?

Answer 1

Probably you need to initialize empty. Do
empty=0;
And really, SO is not a debugging service. So stop asking questions like this.
