Segmentation fault for all elements except the first

booklist1[i] = *(booklist1+i),thenbooklist2[i][j] = *(*(booklist2+i)+j), if j=0, then *(*(booklist2+i)+j) = *(*(booklist2+i)+0) = *(booklist2[i]) = *booklist2[i]

booklist2[0] points to first row, booklist2[1] points to seconds row, and so,... on.

You are defining an array of book pointers (2D array) : book* booklist [MAXBOOKS]
But list is an array of book (1-D array). After execution this statement, lib CurrentLibrary = {3,{list}}; list array will be stored into booklist[0] row. But all other pointers of booklist[1], booklist[2],..... booklist[9] are not pointing to any element. But, you are accessing booklist[1], booklist[2], and booklist[3] in the printLibrary function. This is the reason for Segmentation fault.

For more insight (for 2-D array), please print the following lines:

printf("Title %s\n", library.booklist[0][0].title); prints--> Title The trial printf("Title %s\n", library.booklist[0][1].title); prints--> Title The lurking fear
printf("Title %s\n", library.booklist[0][2].title);prints-->Title Dora's storytime collection

But trying to access, library.booklist[1][0].title will throw segmentation fault, since second row pointer is not pointing to any element.

int main()

    book b_1 = {"The trial","Kafka",101};
    book b_2 = {"The lurking fear","Lovecraft",102};
    book b_3 = {"Dora's storytime collection","Valdes",103};

    book* list = malloc(3*sizeof(book));
    list[0] = b_1; list[1] = b_2; list[2] = b_3;

    lib CurrentLibrary = {3,list}; // list is 1-D array of book
    printLibrary(CurrentLibrary);
    return 0;
}

The output :

Title:The trial
Author:Kafka
Book ID:101
Title:The lurking fear
Author:Lovecraft
Book ID:102
Title:Dora's storytime collection
Author:Valdes
Book ID:103
