c++ programming function error -
my full code (couldn't make smaller) :

*-intellisense: no suitable conversion function "books" "books
*-intellisense: no suitable conversion function "books" "books
-error c2664: 'void choice5(books [],books [],int,int)' : cannot convert argument 1 'books' 'books []
i don't know if it's parameters problem or what!!
the choice5(); function call in main in if(choice==5) after submitting books
and i'm level 1 @ c++ i'm doing best make smaller
i don't know if it's parameters problem or what!!
the compiler tells , problem is: call choice5. first parameter array of books , you're passing in single book.
choice5(new_book[i], aut[j], books_number, aut_number); new_book array, new_book[i] particular book in array. same goes aut.
