How to Call a Function from Another File and Then Print the Return of that Function? (C++)

Question

Complete main() by inserting a new book into each list using the respective LinkedListLibrary and VectorLibrary InsertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each InsertSorted() returns the number of operations the computer performs.

Ex: If the input is:

The Catcher in the Rye

9787543321724

J.D. Salinger

the output is:

Number of linked list operations: 1

Number of vector operations: 1

Where I have been stumped on what to do with this assignment is how do I get the value of the counter, which is supposed to be increasing as operations are completed. When I compile and run the program all I get are 0 for both linked list operations and vector operations.

Am I calling the function in the other file the wrong way?

These are the lines of code that I wrote that are supposed to insert a new book and return the number of operations that it took to do so:

linkedListLibrary.InsertSorted(currNode, linkedListOperations);

vectorLibrary.InsertSorted(tempBook, vectorOperations);

Here is the bottom half of the code that I have so far (The part that I am having trouble with is near the bottom.)

// Insert into linked list

// No need to delete currNode, deleted by LinkedListLibrary destructor

currNode = new BookNode(bookTitle, bookAuthor, bookISBN);

// TODO: Call LL_Library's InsertSorted() method to insert currNode and return

// the number of operations performed

linkedListLibrary.InsertSorted(currNode, linkedListOperations);

linkedListLibrary.lastNode = currNode;

// Insert into VectorList

tempBook = Book(bookTitle, bookAuthor, bookISBN);

// TODO: Call VectorLibrary's InsertSorted() method to insert currNode and return

// the number of operations performed

vectorLibrary.InsertSorted(tempBook, vectorOperations);

// TODO: Print number of operations for linked list

cout << "Number of linked list operations: " << linkedListOperations << endl;

// TODO: Print number of operations for vector

cout << "Number of vector operations: " << vectorOperations << endl;

}

Answer 1

where is vectorOperations getting set?

I do not see the initialization?

somewhere along the line you have to set the counters to zero....

then pass the object, which the routine updates
