the problem is when i call the choice5() function it gets me errors :
*-IntelliSense: no suitable conversion function from "books" to "books
*-IntelliSense: no suitable conversion function from "books" to "books
-error C2664: 'void choice5(books [],books [],int,int)' : cannot convert argument 1 from 'books' to 'books []
i don't know if it's parameters problem or what!!
the choice5(); function call is in the main in the if(choice==5) after submitting books
and i'm like level 1 at c++ so i'm doing my best to make it smaller
i don't know if it's parameters problem or what!!
The compiler tells you exactly what and where the problem is: your call to choice5. The first parameter is an array of books and you're passing in a single book.
choice5(new_book[i], aut[j], books_number, aut_number);
new_book is an array, new_book[i] is a particular book in the array. Same goes for aut.
The function choice5(books new_book[],books aut[], int books_number,int aut_number) must receive as first parameter an array of books or a pointer to a struct books. You will have the same problem with the second parameter "aut". To match with the functioon definiton your call shall have this format :
choice5(new_book, aut, books_number, aut_number)

I'm a novice coding student and trying to create a menu using structs, functions, and switch statements to make a mini database for a class assignment. I'm trying to implant the functions into the switch statements.
I'm getting errors on lines 87 and 137 and I'm not sure where I'm going wrong. Any help, explanation, or correction is much appreciated.

Regarding the error on line 87 (getline(cin, moviedb[n].cast[i]);) :
moviedb[n].cast[i] is a std::string*, not std::string like you might have meant.
A quick compilation fix would be to use:
getline(cin, *(moviedb[n].cast[i]));
i.e. dereference the pointer.
However - this code raises other design/programming issues:
Why do you use std::string* and not std::string in the first place.
Why do you use C style array instead of std::vector (or std::array if you can commit to the size). This is relevant for both: string *cast[10]; and EZTechMovie moviedb[100];
I'm trying to store multiple structs into an file and my problem is that when I try to add 2 structs into the same file, my second struct overwrites my first struct and when I go print out my first struct, its print out my second struct.

You are writing everything to the beginning of the file, so of course multiple writes overwrite eachother.
You need to define a file format that can contain multiple records and a way to find where to write new records that doesn't overlap with previous ones, as well as an easy way to find the location of existing records.
Have you considered just using a SQL (or other type of) database?
hello guys i'm trying to delete a full line from a ".txt" file when the user enters the book id
my text file looks like this :

Read the whole file into a memory buffer. Delete what you don't want. Overwrite the existing file with the contents of your memory buffer.
You've now deleted what you did not want from the file.
Not under standing looping for arrays. Looping through all of grab some or search. Can someone explain the process? Thanks in advance. Sorry if duplicate. I looked around and couldnt find a solid explaination that I could understand.

In C++ arrays lose attributes when passed to functions. Those attributes are capacity and size (number of filled slots). You will need to pass this additional information for each array:
void addName(string names[], unsigned int names_capacity, unsigned int names_size,
string phones[], unsigned int phones_capacity, unsigned int phones_size)
To get around this, you can use std::vector. The std::vector knows its capacity and size, so you don't have to pass additional attributes to your function.
Also, if you use tolower or toupper before you compare, you only need to make one comparison:
char input;
cout << "Do you have another contact to add? y or n" << endl;
cin >> input;
input = toupper(input);
if(input == 'Y')
When using strings, you can convert them to all uppercase or all lowercase by using std::transform, such as:
std::transform(input.begin(),
input.begin(), input.end(),
tolower);
Sorry for the lack of previous explanation to my school's assignment. Here's what I'm working with and what I have / think I have to do.
I have the basic structure for populating the address book inside an array, however, the logic behind populating a text file is a bit beyond my knowledge. I've researched a few examples, however, the implementation is a bit tricky due to my novice programming ability.
I've gone through some code that looks relevant in regard to my requirements:
ifstream input("addressbook.txt");
ofstream out("addressbook.txt");
For ifstream, I believe implementing this into the voidAddBook::AddEntry() would work, though I've tried it and the code failed to compile, for multiple reasons.
For ostream, I'm lost and unsure as to how I can implement this correctly. I understand basic file input and output into a text file, however, this method is a bit more advanced and hence why I'm resorting to stackoverflow's guidance.

As it currently stands, I'm still stuck. Here's where I believe I should start:
cout << "Please enter your selection (1-4) and press enter: ";
cin >> num;
cout << endl;
if (num == 1)
AddressBook.AddEntry();
else if (num == 2)
AddressBook.SearchLast();
else if (num == 3)
AddressBook.DispAll();
else if (num == 4)
BoolQuit = true;
//save first name
//save last name
//save dob
//save phone number
//save email
//exit
else
cout << "Please enter a number (1-4) and press enter: " << endl;
cout << endl;
}
Somehow, during menu option 4 the array should dump the data into a .txt file and arrange it in a way that it can be easily imported upon reloading the program. I'm a little confused as to how I can store the array data from each character array into a .txt file.
Well first, if the input is coming from the file input, then instead of doing cin >> x you would have to do input >> x. If it's coming from standard input (the keyboard), then you can use cin.
Also, your else if statement should be something like this:
while (true)
{
// ...
else if (num == 4)
{
for (int i = 0; i < AddressBook.count; ++i)
{
AddBook::EntryStruct data = AddressBook.entries[i];
out << data.FirstName << " " << data.LastName
<< std::endl
<< data.Birthday << std::endl
<< data.PhoneNum << std::endl
<< data.Email;
}
}
break;
