Binary files The binary file data.dat contains characters and numbers- it has 16 characters, followed by numbers of type int alternating with numbers of type double -so after the first 16 characters, there will be an int, followed by a double, followed by an int, followed by a double, and so on. Write a program to open the file and until the end of file is reached, read in the values in the appropriate data types (that is, read...

I am writing a program in C++, which requires me to read an input text file using command line argument. However, I am using xcode on my Macbook to write C++ program, and use terminal instead of command. How do you use int main(int argc, char** argv[]) to read an input file. My professor requires us not to hard code the text file name like .open("example.txt"); Thank you!
MUST BE ANSWERED BY USING C++ Question 1 Unsorted List Implement a template class UnsortedList as defined by the following skeleton: #define MAX_ITEMS 10 typedef char ItemType; class UnsortedList { private: int length; ItemType values[MAX_ITEMS]; int currentPos; public: SortedList( ); // default constructor: lenght=0, currentPos=-1 void MakeEmpty; // let length=0 void InsertItem(ItemType x); // insert x into the list void DeleteItem(ItemType x); // delete x from the list bool IsFull( ); // test...
QUESTION The ReadFile class opens and reads a text file. The WriteFile class opens and writes to a file. Compile and run these programs. There are several ways to read/write text files. The examples shown here are just one way of achieving this. Look at the API for the BufferedReader class. The readline() method is a simple way to read the text file line by line. It returns null when the end of the file has been reached. https://docs.oracle.com/javase/8/docs/api/java/io/BufferedReader.html Look...
I need help with the following question:
P5: The program below has a parent thread that is a writer and 2 child threads that are both readers. Complete the "child" function so that readers can continuously print the value of x" whenever the writer is not writing. No reader should starve while the other reader is reading sem t mutex, Xw mutex; int x; int read count = 0; int main (int argc, char "argv[]) { sem init (&mutex, 0,...
A binary tree is a complete binary tree if all the internal nodes (including the root node) have exactly two child nodes and all the leaf nodes are at level 'h' corresponding to the height of the tree. Consider the code for the binary tree given to you for this question. Add code in the blank space provided for the member function checkCompleteBinaryTree( ) in the BinaryTree class. This member function should check whether the binary tree input by the...

The purpose of this is to use inheritance, polymorphism, object
comparison, sorting, reading binary files, and writing binary
files. In this application you will modify a previous project. The
previous project created a hierarchy of classes modeling a company
that produces and sells parts. Some of the parts were purchased and
resold. These were modeled by the PurchasedPart class. Some of the
parts were manufactured and sold. These were modeled by the
ManufacturedPart class. In this you will add a...
