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.
