Short Answer

Expert verified
Answer: `std::ofstream people;`

Step by step solution

01

Introduction to File Stream Objects

A file stream object facilitates reading and writing data into a file. In this exercise, we need to create a file stream object that will be used for output. To do this, we can include the fstream header at the beginning of the program. The header provides file stream declarations that allow us to create file stream objects.
02

Creating a File Stream Object for File Output

To create a file stream object, we can use the ofstream class, which is provided by the fstream header. It is necessary to create an ofstream object to connect our program to a file for output. In this case, we will name the object "people". Here is the statement to create a file stream object named "people": ```cpp std::ofstream people; ``` After creating the "people" file stream object, you can open a file for output, write data to the file, and close the file once the operation is complete.

The __ member function returns a file's current read position.

Suppose that you have two text files that contain sequences of integers separated by white space (blank space, tabs, and line breaks). The integers in both files appear in sorted order. with smaller values near the beginning of the file and large values closer to the end. Write a pseudocode algorithm that merges the two sequences into a single sorted sequence that is written to a third file.

The ___ member function moves a file's write position to a specified byte in the file.

The same formatting techniques used with ___ may also be used when writing information to a file.

Give a pseudocode algorithm for determining the length of a file; that is, the number of bytes that are stored in the file.
